The C-Reactive Protein (CRP) Test measures CRP levels in blood to detect inflammation in the body. Elevated CRP may indicate infections, autoimmune disorders, or chronic diseases such as arthritis, cardiovascular disease, or inflammatory bowel disease. Doctors use this test to assess acute illness, monitor treatment response, and evaluate risk for heart disease. The CRP test provides key insight into inflammation, immune health, and overall wellness.

The High-Sensitivity C-Reactive Protein (hs-CRP) Test measures very low levels of CRP in blood to evaluate inflammation and cardiovascular risk. Elevated hs-CRP may indicate increased risk for heart disease, heart attack, or stroke even before symptoms appear. Doctors use this test along with cholesterol and other markers to assess overall heart health, guide prevention strategies, and monitor treatment. It also helps evaluate chronic inflammation and metabolic conditions.

: Serum
Also Known As: Cardiac CRP Test, High Sensitivity C-Reactive Protein Test

The Cardio IQ Vitamin D test, also known as a 25-hydroxy vitamin D test, measures the levels of total vitamin D in the blood, including both vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). It provides information about an individual's overall vitamin D status.

: Serum
Also Known As: Ergocalciferol Test, Vitamin D2 Test, Cholecalciferol Test, Vitamin D3 Test, Calcidiol Test, 25-hydroxyvitamin D Test, Calcifidiol Test, 25-hydroxy-vitamin D Test

The Carnitine test is a specialized laboratory assay designed to measure the concentration of carnitine—a vital compound—in the blood. Carnitine plays a crucial role in the transport of fatty acids into the mitochondria, the energy-producing centers of cells. This test offers insights into carnitine deficiency and metabolic abnormalities that affect energy metabolism.
: Serum

The Celiac Disease Comprehensive Panel test is a blood test designed to diagnose celiac disease, an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. This comprehensive panel consists of multiple tests that help healthcare providers accurately diagnose or rule out celiac disease in individuals suspected of having the condition.
Also Known As: Comprehensive Celiac Disease Panel

The Estradiol (E2) Test measures levels of estradiol, the primary form of estrogen, to evaluate reproductive and hormonal health. It helps assess menstrual irregularities, fertility issues, menopause status, and estrogen-producing disorders. In men, it aids in diagnosing hormonal imbalances. Doctors use the estradiol test to monitor hormone therapy, ovarian function, and conditions affecting puberty, bone health, and overall endocrine balance.

The Glucose Test measures blood sugar levels to evaluate energy metabolism and screen for diabetes or prediabetes. Abnormal glucose may indicate hyperglycemia, hypoglycemia, or metabolic disorders. Doctors use this test during routine exams, to investigate symptoms like fatigue, excessive thirst, or frequent urination, and to monitor treatment for diabetes. It provides essential insight into how the body regulates blood sugar and overall metabolic health.

: Serum
Also Known As: Fasting Glucose Test, Fasting Blood Sugar Test

The Hemoglobin A1c (HbA1c) Test measures average blood glucose over 2–3 months by detecting sugar attached to hemoglobin in red blood cells. It is used to diagnose diabetes, identify prediabetes, and monitor long-term blood sugar control. Doctors rely on the HbA1c test to evaluate treatment effectiveness, guide adjustments, and assess risk for complications, making it essential for diabetes care and metabolic health screening.

Also Known As: A1c Test, HbA1c Test, Glycated Hemoglobin Test

Most Popular

The Homocysteine Test measures homocysteine levels in blood to assess risk for heart disease, stroke, and vascular problems. Elevated homocysteine may result from vitamin B6, B12, or folate deficiency and is linked to blood clots, cognitive decline, and osteoporosis. Doctors use this test to evaluate cardiovascular risk, monitor nutritional deficiencies, and guide treatment for metabolic or genetic conditions affecting homocysteine metabolism.

The Insulin Test measures insulin levels in blood to assess how the body regulates glucose and metabolism. It helps diagnose insulin resistance, hypoglycemia, type 2 diabetes, and metabolic syndrome. Doctors also use it to evaluate pancreatic function and monitor treatment effectiveness. Frequently ordered with glucose testing, the insulin test provides critical insight into endocrine health, blood sugar control, and risk for diabetes-related complications.

Also Known As: Fasting Insulin Blood Test

The Lyme Disease Ab Test with Reflex to Blot IgG/IgM screens for antibodies to Borrelia burgdorferi, the bacteria causing Lyme disease. If positive or equivocal, results reflex to a confirmatory Western Blot for IgG and IgM. This test helps diagnose early or late Lyme disease, supporting timely treatment and monitoring of infection in patients with tick exposure or symptoms.

: Serum
Also Known As: Borrelia burgdorferi Test, Lyme Disease Antibodies IgG IgM Immunoblot Test, Lyme Disease Ab Test

The Lyme Disease IgG IgM Antibodies Immunoblot Test detects antibodies to Borrelia burgdorferi, the bacteria causing Lyme disease. IgM indicates recent infection, while IgG suggests past or ongoing infection. Doctors order this test to confirm exposure after ELISA screening or when symptoms such as rash, fatigue, joint pain, or neurological issues appear. Results provide critical insight for diagnosing and managing Lyme disease with greater accuracy.

Also Known As: Borrelia burgdorferi Test, Lyme Disease Antibodies Test

 The Lyme Disease IgG Antibody Immunoblot test, often referred to as the Lyme Western Blot, is a laboratory test used to detect antibodies against the bacterium Borrelia burgdorferi, the causative agent of Lyme disease. It is a highly specific method that can detect and visualize antibodies targeting individual protein components of the bacterium.

The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests. Magnesium is vital for muscle and nerve function, energy production, bone strength, and heart health. This test helps detect deficiencies or imbalances from poor diet, absorption issues, or medical conditions, supporting overall wellness.

Patient must be 18 years of age or older.
