The VLDL Cholesterol Test measures very low-density lipoprotein cholesterol, which carries triglycerides in the blood. High VLDL levels are linked to heart disease, atherosclerosis, and metabolic syndrome. Doctors order this test as part of a lipid panel to assess cardiovascular risk, monitor treatment, or evaluate high triglycerides. Results provide critical insight into lipid metabolism, helping guide lifestyle changes, therapy, and long-term heart health management.

The Leptin Test measures leptin hormone levels in blood to evaluate metabolism, appetite regulation, and body fat balance. Abnormal levels may indicate obesity, metabolic syndrome, insulin resistance, or leptin deficiency. Doctors use this test to assess unexplained weight gain, difficulty losing weight, or potential endocrine disorders. It also supports research on energy balance, fertility, and overall metabolic health management.

The C-Peptide Test measures C-peptide levels in blood to assess insulin production and pancreatic function. Low levels may indicate type 1 diabetes or reduced insulin production, while high levels may suggest type 2 diabetes, insulin resistance, or insulinoma. Doctors use this test to differentiate diabetes types, monitor treatment, and evaluate unexplained hypoglycemia. It provides key insight into endocrine, pancreatic, and metabolic health.

The Cardio IQ™ Apolipoprotein A1 Test measures ApoA1, the main protein in HDL cholesterol. Higher ApoA1 levels are generally linked to lower cardiovascular risk. This test helps evaluate heart health, lipid metabolism, and supports assessment of cardiovascular disease risk.

The Cardio IQ™ Apolipoprotein B Test measures ApoB, the main protein in LDL and other atherogenic lipoproteins. Elevated ApoB levels are linked to higher cardiovascular risk. This test provides a more precise assessment of heart disease risk than standard cholesterol tests and helps guide treatment decisions.

The Fructosamine Test measures average blood glucose levels over the past 2–3 weeks by evaluating glycated proteins. Unlike the HbA1c test, which reflects long-term control, this test provides a shorter-term view, making it useful for monitoring recent treatment changes, pregnancy, or conditions affecting red blood cells. Doctors use it to assess diabetes management, adjust medications, and evaluate how well blood sugar is being controlled.
