This test measures cholesterol levels in peritoneal dialysate fluid, the fluid used during peritoneal dialysis treatment for kidney disease. Cholesterol in dialysate can indicate peritoneal membrane problems or nutritional issues in dialysis patients. While not a standard screening test for cardiovascular risk, it provides information specific to dialysis adequacy and peritoneal membrane function. Elevated levels may suggest membrane changes or metabolic complications.

This test measures glucose concentration in peritoneal dialysate fluid, the solution used during peritoneal dialysis for kidney failure. Glucose naturally diffuses from the dialysate into the bloodstream during treatment, and measuring residual glucose helps assess dialysate dwell time and treatment effectiveness. Changes in dialysate glucose levels can indicate peritoneal membrane changes or absorption problems affecting dialysis adequacy and treatment outcomes.

This test detects antibodies against myeloperoxidase (MPO), an enzyme in certain white blood cells. Elevated MPO antibodies are associated with ANCA-associated vasculitis, a serious autoimmune disease that causes inflammation of blood vessels. MPO-ANCA is one form of this condition. Positive results help diagnose vasculitis and guide treatment with immunosuppressive therapies. This test is particularly important for patients with unexplained kidney disease, lung problems, or multi-system inflammation.

Fibrinogen is a protein produced by the liver that plays a critical role in blood clotting. When you bleed, fibrinogen is converted into fibrin, which forms the mesh that stops bleeding. A fibrinogen test measures the amount of this clotting protein in your blood. Abnormally low levels may indicate bleeding disorders or liver disease, while elevated levels can increase clot formation risk and are associated with cardiovascular disease, stroke, and inflammation.

Homocysteine is an amino acid produced during protein metabolism. Elevated blood homocysteine, called hyperhomocysteinemia, is an independent risk factor for cardiovascular disease, stroke, and blood clots. High levels may indicate deficiencies in vitamins B12, B6, or folate, kidney disease, or genetic factors affecting homocysteine metabolism. This test helps identify cardiovascular risk and vitamin deficiencies. Lowering homocysteine through B-vitamin supplementation or dietary changes may reduce heart disease and stroke risk.

Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle with a genetic component that significantly influences cardiovascular risk. This test measures Lp(a) as a percentage of total lipoprotein, providing insight into your atherogenic lipid profile. High Lp(a) levels are an independent risk factor for heart attack and stroke, even in people with otherwise normal cholesterol. Unlike other lipids, Lp(a) is largely determined by genetics and is less responsive to diet and exercise, making it important for personalized heart disease risk assessment.

B-type natriuretic peptide (BNP) is a hormone released by heart chambers when they stretch from increased pressure or fluid overload. Blood BNP levels are a key marker of heart stress and fluid balance. Elevated BNP strongly suggests heart failure, even before symptoms appear, and helps doctors assess disease severity and treatment response. The test is also useful for distinguishing heart-related causes of shortness of breath from lung problems. BNP is one of the most sensitive tests for detecting heart dysfunction and guides treatment decisions in cardiovascular patients.

HDL-2 is a specific subtype of 'good' cholesterol that is particularly protective against heart disease. This specialized test uses ultracentrifugation to isolate and measure HDL-2 cholesterol specifically. Higher HDL-2 levels are associated with better cardiovascular health and lower risk of heart attack and stroke. While standard cholesterol panels measure total HDL, this advanced test provides more detailed information about HDL quality, helping clinicians assess detailed cardiovascular risk in patients with metabolic concerns or significant family histories of heart disease.

A descreased ratio of eiscospentaenoate/arachidonate is a well recognized predictor of cardiovascular disease.[PMID: 24976364]

This test detects IgE antibodies against brewer's yeast proteins, indicating a potential yeast allergy. Brewer's yeast is used in fermented foods and beverages including beer, wine, and some breads. A positive result suggests you may experience allergic symptoms—ranging from mild itching or hives to gastrointestinal symptoms—after consuming yeast-containing foods. This test helps identify yeast as an allergy trigger, useful for those with suspected yeast sensitivity.

This advanced test measures the proportion of cholesterol carried by HDL 3c, a specific subtype of HDL (good cholesterol). HDL particles vary in size and density; larger HDL particles are considered more protective against heart disease. By analyzing the cholesterol distribution within HDL subclasses, this test provides detailed insight into the quality of your HDL, which may offer a more nuanced picture of cardiovascular risk than standard HDL testing alone.

C-reactive protein (CRP) is an acute-phase protein produced by the liver in response to inflammation. Measured in serum or plasma, CRP is one of the most widely used markers of systemic inflammation. It rises rapidly (within hours) in response to bacterial infections, autoimmune flares, tissue injury, and malignancy. High-sensitivity CRP (hs-CRP) at lower levels is used for cardiovascular risk stratification. CRP is valuable for monitoring treatment response in rheumatologic conditions, infections, and post-surgical recovery. Unlike ESR, CRP responds quickly to changes in inflammatory status.

Insulin is a hormone produced by the pancreas that regulates blood glucose levels by allowing cells to absorb sugar for energy. An insulin test measures circulating insulin levels, which rise after eating or during fasting depending on metabolic function. Elevated fasting insulin may indicate insulin resistance, where cells don't respond properly to insulin, increasing risk for prediabetes and metabolic syndrome. Low insulin levels may suggest pancreatic dysfunction or diabetes.

This test measures the proportion of cholesterol in HDL 3a particles relative to total HDL cholesterol. HDL subfractions—including the smaller HDL 3a particles—have different cardiovascular protective effects. HDL 3a particles are generally smaller and less cardioprotective than larger HDL 2 particles. This ratio provides insight into HDL quality and particle composition, which may offer additional cardiovascular risk assessment beyond traditional HDL cholesterol levels.

Medium-sized beta lipoprotein subparticles are components of LDL (low-density lipoprotein) cholesterol. Advanced lipid tests measure the size and number of these particles, providing more detailed information than standard cholesterol tests. Increased levels of small, dense LDL particles are associated with greater cardiovascular risk, as these particles more easily penetrate artery walls. This test helps identify individuals at higher heart disease risk despite normal total cholesterol levels.

Thyroid stimulating hormone (TSH) is produced by the pituitary gland and regulates thyroid hormone production. A TSH test is the primary screening tool for thyroid disorders. Elevated TSH suggests an underactive thyroid (hypothyroidism), while low TSH may indicate an overactive thyroid (hyperthyroidism). Thyroid function affects metabolism, energy, weight, and mood. This is one of the most frequently ordered tests because thyroid dysfunction is common and affects overall health.

This test measures the ratio of omega-6 to omega-3 fatty acids in your blood—both essential fats crucial for health. The ratio reflects your dietary balance: excessive omega-6 relative to omega-3 may promote inflammation, while a lower ratio is generally considered healthier. Modern diets often contain too much omega-6 (from vegetable oils, processed foods) and too little omega-3 (from fish, flaxseed). Optimizing this ratio supports heart, brain, and joint health.

This test measures small, dense LDL cholesterol particles, a subset of low-density lipoprotein. Small, dense LDL particles are more atherogenic (damage-prone) than larger LDL particles and penetrate artery walls more easily, increasing cardiovascular risk. Elevated small dense LDL is associated with metabolic syndrome, insulin resistance, low HDL, and elevated triglycerides. This test provides more detailed cardiovascular risk assessment than standard LDL measurement alone, particularly useful for individuals with metabolic risk factors or family history of heart disease.

Non-HDL cholesterol represents all cholesterol particles except beneficial HDL cholesterol, including LDL and other atherogenic particles that contribute to plaque buildup in arteries. Unlike total cholesterol, non-HDL is considered a better predictor of cardiovascular risk because it measures the 'bad' cholesterol more accurately. Elevated non-HDL cholesterol increases risk of heart attack and stroke, particularly in people with high triglycerides or metabolic syndrome. Managing non-HDL through diet, exercise, and sometimes medication is important for heart health.

Cystatin C is a protein produced by all cells in your body at a relatively constant rate and filtered by the kidneys into urine. Measuring urine cystatin C levels helps assess kidney filtration function. Unlike creatinine, cystatin C is less affected by muscle mass and certain medications, making it a valuable marker for detecting early kidney disease or monitoring kidney function changes. This test is often used alongside other kidney markers to provide a more complete picture of kidney health.

Remnant lipoproteins are cholesterol-rich particles that remain after triglycerides are removed from dietary particles in the bloodstream. Elevated remnant lipoprotein levels indicate impaired cholesterol metabolism and are associated with increased cardiovascular risk, independent of traditional cholesterol levels. High remnant lipoproteins suggest metabolic dysfunction, poor diet quality, or genetic predisposition. This test provides insight into heart disease risk beyond standard lipid panels and may warrant lifestyle changes or medication.

This test calculates the ratio between LDL cholesterol (the 'bad' kind that builds up in arteries) and HDL cholesterol (the 'good' kind that protects your heart). Rather than looking at each individually, this ratio provides a comprehensive picture of your cardiovascular risk. A lower ratio is healthier, indicating better heart protection. This metric is often considered more predictive of heart disease risk than LDL or HDL levels alone, making it valuable for assessing overall cardiovascular health.

Lipoprotein midband B is an uncommon lipoprotein particle detected through specialized lipid testing. Its presence or elevation can indicate certain metabolic disorders or dyslipidemia patterns not visible on standard cholesterol panels. This test is typically ordered when routine lipid results are abnormal or when a patient has unusual cardiovascular risk factors despite normal standard cholesterol levels. Results help refine cardiovascular risk assessment and guide specialized lipid-lowering therapy if needed.

This test measures the amount of cholesterol carried specifically by LDL (low-density lipoprotein) particles, the 'bad' cholesterol that can accumulate in artery walls. Unlike standard LDL tests, this advanced method directly measures LDL cholesterol separately from other similar particles, providing a more accurate assessment. Elevated LDL cholesterol is a key risk factor for heart disease and stroke. This test helps guide treatment decisions and monitor the effectiveness of cholesterol-lowering therapies.

Linoleate is an omega-6 polyunsaturated fatty acid essential for brain function, hormone production, and cell structure. Your body cannot produce it, so you must obtain it from foods like vegetable oils, nuts, and seeds. Blood linoleate levels reflect your intake and nutritional status. While omega-6 fatty acids are essential, high ratios compared to omega-3 fatty acids may promote inflammation. This test helps assess fatty acid balance and nutritional adequacy, particularly for those monitoring inflammatory conditions.

Docosahexaenoate (DHA) is an omega-3 polyunsaturated fatty acid crucial for brain health, eye function, and reducing inflammation. Your body produces small amounts from plant sources, but most comes from fish and seafood or supplements. Blood DHA levels reflect your intake and omega-3 status. Low DHA is associated with cognitive decline, depression, and increased cardiovascular risk. This test is particularly useful for monitoring supplementation, assessing cardiovascular risk, or investigating cognitive or mood concerns.

Eicosapentaenoate (EPA) is an omega-3 polyunsaturated fatty acid that reduces inflammation, supports heart and brain health, and helps regulate mood and immune function. Like DHA, EPA primarily comes from fatty fish, seafood, and supplements. Blood EPA levels reflect your dietary intake and omega-3 status. Higher EPA is associated with better cardiovascular health and lower depression risk. This test monitors omega-3 supplementation effectiveness and assesses inflammation and cardiovascular risk.

Omega-3 fatty acids are essential polyunsaturated fats that reduce inflammation, support heart and brain health, and regulate immune function. Your body cannot produce them, so they must come from dietary sources like fatty fish, flaxseed, and walnuts, or supplements. Blood omega-3 levels reflect your dietary intake and nutritional status. Higher omega-3 levels are associated with better cardiovascular health, lower depression risk, and reduced inflammation. This test assesses overall omega-3 status and guides supplementation decisions.

Omega-6 fatty acids are essential polyunsaturated fats found in oils, nuts, and seeds that your body needs but cannot produce on its own. This test measures the levels of omega-6 in your blood. While omega-6 is necessary for brain function and skin health, an imbalanced ratio of omega-6 to omega-3 fatty acids may promote inflammation. Most Western diets are high in omega-6, potentially contributing to chronic inflammatory conditions. This test helps assess your fatty acid balance and dietary patterns.

LDL cholesterol particles vary in size, and particle size pattern affects cardiovascular risk. Large, buoyant LDL particles are less atherogenic (less damaging to arteries), while small, dense LDL particles are more atherogenic. This test identifies your predominant LDL particle size pattern, providing insight beyond standard cholesterol measurements. A predominance of small, dense LDL particles is associated with higher cardiovascular risk, even with normal total LDL cholesterol. This test helps refine risk assessment and guide targeted interventions.

Apolipoprotein B (ApoB) is the main protein component of LDL cholesterol particles and other atherogenic lipoproteins. Unlike standard cholesterol testing, ApoB directly counts the number of atherogenic particles in your blood, providing a more accurate cardiovascular risk assessment. One ApoB protein sits on each particle regardless of size, making ApoB a superior predictor of heart attack and stroke risk. This test is increasingly recommended for better cardiovascular risk stratification, particularly in people with metabolic syndrome or family history of early heart disease.

This test detects IgE antibodies against egg white allergens in your blood. Egg allergy is common in children but can persist into adulthood. Reactions range from oral itching and hives to gastrointestinal symptoms and anaphylaxis in severe cases. A positive test confirms egg allergy and guides dietary avoidance of eggs and egg-containing products. Note that some individuals can tolerate cooked eggs (where proteins are altered) even if they react to raw eggs, so reactions may vary by food form.

Hemoglobin A1c measures the percentage of hemoglobin (in red blood cells) that has glucose attached to it. Since red blood cells live about 3 months, HbA1c reflects your average blood glucose over the past 2-3 months. Unlike a single fasting glucose test, HbA1c provides a comprehensive picture of long-term glucose control. It's the gold standard for diagnosing and monitoring diabetes, and elevated levels indicate prediabetes or diabetes.

This test measures total 25-hydroxyvitamin D, combining both vitamin D2 (from foods and supplements) and vitamin D3 (from sun exposure and food). The 25-hydroxy form is the best indicator of overall vitamin D status because it reflects total body stores. This single measurement efficiently assesses vitamin D adequacy for bone health, immune function, and calcium regulation without measuring multiple vitamin D forms.

GFR measures how efficiently your kidneys filter waste from blood, expressed as milliliters of filtrate per minute. It's calculated using creatinine levels adjusted for age, sex, and body size. GFR is the most accurate indicator of kidney function, with different stages indicating mild, moderate, or severe kidney disease. Even small declines in GFR can signal progressive kidney disease requiring monitoring and lifestyle modifications to slow progression.
