Rheumatoid Arthritis

The Creatine Kinase (CK) Total Test measures CK enzyme levels in blood to detect muscle injury, inflammation, or stress. Elevated CK may indicate muscle disorders, heart attack, strenuous exercise, or conditions such as rhabdomyolysis, while low levels are less common. Doctors use this test to evaluate unexplained muscle pain, weakness, or chest pain and to monitor recovery. It provides insight into muscle, cardiac, and overall metabolic health.

The DHEA Sulfate (DHEA-S) Test measures levels of DHEA-S, a hormone made by the adrenal glands, to evaluate adrenal function and hormone balance. It helps detect adrenal tumors, hyperplasia, or insufficiency and assess abnormal hair growth, infertility, or early/late puberty. Doctors also use it to investigate irregular menstrual cycles, monitor androgen disorders, and evaluate symptoms of hormone imbalance affecting reproductive and metabolic health.

The Ferritin Test measures ferritin, a protein that stores iron in the body, to evaluate iron levels and detect deficiency or overload. It helps diagnose anemia, iron deficiency, hemochromatosis, and chronic disease-related inflammation. Doctors often order the ferritin test to investigate fatigue, weakness, or unexplained symptoms. It is also used to monitor iron supplementation, treatment effectiveness, and overall iron metabolism health.

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.

The Immunoglobulin A (IgA) Test measures IgA antibody levels in blood to evaluate immune system health and mucosal defense in the respiratory and digestive tracts. Low IgA may indicate immune deficiency, celiac disease, or recurrent infections, while high levels may suggest autoimmune disorders, liver disease, or chronic inflammation. Doctors use this test to assess unexplained illness or immune imbalance. Results provide key insight into antibody function and overall immunity.

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.

The Lipid Panel with Ratios Test measures seven key markers: total cholesterol, HDL, LDL, non-HDL cholesterol, triglycerides, Chol/HDL ratio, and LDL/HDL ratio. This advanced panel evaluates cardiovascular risk by assessing cholesterol balance and fat metabolism. Doctors use it to detect high cholesterol, atherosclerosis risk, and heart disease, and to monitor treatment. Often part of routine exams, it provides insight into long-term heart and metabolic health.

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.

The Protein Total and Albumin Test measures overall protein levels and albumin, the main blood protein made by the liver. Abnormal levels may indicate liver disease, kidney disorders, malnutrition, or chronic inflammation. Doctors order this test for patients with swelling, fatigue, or abnormal lab results. Results provide critical insight into nutritional status, liver and kidney function, and help guide diagnosis and treatment of metabolic or chronic conditions.

The RNP Antibody Test detects antibodies to ribonucleoprotein, an autoantigen linked to connective tissue and autoimmune diseases. Elevated levels may indicate mixed connective tissue disease, systemic lupus erythematosus, or other autoimmune disorders. This test provides valuable insight into immune system activity and is often performed alongside ANA and ENA panels for a broader evaluation of autoimmune health.

The Salicylate Test measures salicylate levels in the blood to evaluate therapeutic use or potential toxicity from aspirin and related medications. Elevated concentrations may indicate overdose, metabolic disturbance, or risk of salicylate poisoning. This test supports monitoring in patients treated for pain, inflammation, or cardiovascular conditions and helps guide clinical management of suspected overdose cases.

The Testosterone Free and Total Test measures total testosterone and free, bioavailable testosterone in blood for both men and women. It helps diagnose hormone imbalance, infertility, low libido, erectile dysfunction in men, irregular periods, or PCOS in women. Doctors also order it to assess fatigue, mood changes, or muscle weakness and to monitor hormone therapy. This test provides key insight into reproductive, endocrine, and overall metabolic health.

The Thiopurine Metabolites Test evaluates active metabolites of thiopurine drugs, including 6-thioguanine nucleotides and 6-methylmercaptopurine, to assess treatment effectiveness and safety. Elevated or low metabolite levels may indicate risk of toxicity, under-dosing, or non-adherence. This test provides critical insight for managing patients on immunosuppressive therapy, guiding personalized dosing, and monitoring long-term response.

The Total Glutathione Test measures glutathione, a key antioxidant that protects cells from oxidative stress and supports liver detoxification, immune defense, and cellular repair. Low levels may indicate chronic illness, toxin exposure, poor nutrition, or high oxidative stress, while high levels may reflect supplementation. Doctors use this test to assess antioxidant capacity, monitor therapy, and guide treatment for overall metabolic and immune health.

The Thyroid Stimulating Hormone (TSH) Test measures TSH levels in blood to assess thyroid function and diagnose hypothyroidism or hyperthyroidism. It evaluates how the thyroid controls metabolism, energy, weight, and heart rate. Doctors use the TSH test to investigate symptoms such as fatigue, hair loss, or mood changes. Frequently included in routine health exams, it is also key for monitoring thyroid disease treatment and overall endocrine balance.

The Vitamin B12 Micronutrient Test measures blood levels of vitamin B12, essential for red blood cell production, nerve health, and DNA synthesis. Deficiency can cause anemia, fatigue, neurological issues, and cognitive changes. This test helps identify dietary deficiencies, absorption problems, or related health conditions, supporting diagnosis and ongoing management of overall wellness.

Patient must be 18 years of age or older.

The Vitamin B12 Test measures cobalamin levels in blood to evaluate nutritional health, red blood cell production, and nervous system function. Low B12 can cause anemia, fatigue, weakness, memory problems, and nerve damage, while high levels may indicate liver or kidney disease. Doctors use this test to detect B12 deficiency, monitor treatment, and assess malabsorption conditions like pernicious anemia, Crohn’s disease, or celiac disease.

The Vitamin D 25-Hydroxy Total Test measures levels of 25-hydroxyvitamin D in blood to evaluate vitamin D status, bone health, and calcium balance. It helps detect deficiency, insufficiency, or toxicity, which can affect immune function, muscle strength, and risk of osteoporosis. Doctors use this test to assess overall nutritional health, monitor supplementation, and support diagnosis of metabolic or endocrine disorders linked to vitamin D.

The Methylation Essentials Panel provides a comprehensive baseline evaluation of core laboratory markers involved in the body’s methylation process. Methylation is a fundamental biochemical pathway that supports nutrient metabolism, cardiovascular wellness, energy production, and cellular maintenance.
