The Epstein-Barr Virus (EBV) Comprehensive Panel measures VCA IgM, VCA IgG, EBNA IgG, and Early Antigen D IgG antibodies to evaluate stage of EBV infection. This virus causes mononucleosis and has links to chronic fatigue, autoimmune conditions, and certain cancers. Doctors order this test for patients with fever, sore throat, lymph node swelling, or prolonged fatigue. Results help distinguish acute, past, or reactivated EBV infection and guide clinical care.

The Coxsackie B Virus Antibodies test is a diagnostic blood test used to detect antibodies produced by the immune system in response to a Coxsackie B virus infection. Coxsackie B viruses belong to the enterovirus family and are associated with a range of illnesses, from mild flu-like symptoms to more severe conditions such as viral myocarditis and meningitis. This test measures the presence of specific antibodies against Coxsackie B viruses, helping to confirm recent or past infections and assess the immune response to the virus. The test is particularly useful in identifying cases where Coxsackie B virus may be the underlying cause of unexplained cardiac, neurological, or systemic symptoms.

The T3 Reverse (rT3) Test measures reverse triiodothyronine, an inactive thyroid hormone, to assess thyroid and metabolic function. High rT3 may occur in hypothyroidism, chronic illness, stress, or during certain treatments, while low levels may reflect hormone imbalance. Doctors use this test along with TSH, Free T4, and Free T3 to evaluate fatigue, weight changes, or slow metabolism. The rT3 Test provides insight into thyroid regulation, energy balance, and endocrine 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 Epstein-Barr Virus Antibody (EBV) Panel detects antibodies to EBV, including VCA IgM, VCA IgG, and EBNA IgG, to determine current, recent, or past infection. EBV causes infectious mononucleosis and has links to chronic fatigue and certain cancers. Doctors order this test for patients with fever, sore throat, swollen lymph nodes, or fatigue. Results help identify stage of infection, confirm diagnosis, and guide clinical management of EBV-related illness.

The Epstein-Barr Virus (EBV) Early Antigen D IgG Antibody Test detects IgG antibodies to EBV’s early antigen, helping identify recent or reactivated infection. Elevated levels may indicate acute mononucleosis, viral reactivation, or chronic EBV. Doctors order this test when patients present with fatigue, fever, sore throat, or swollen lymph nodes. Results provide key insight into EBV activity, supporting diagnosis, monitoring, and treatment decisions.

The Cortisol Saliva Test with 3 samples measures cortisol levels at three points in the day to evaluate adrenal function and circadian rhythm. Tracking this stress hormone provides insight into adrenal insufficiency, Cushing’s syndrome, Addison’s disease, and hormone imbalance, while supporting assessment of stress response, metabolic health, and endocrine system regulation.

The Candida Albicans (M5) IgE Test measures IgE antibody response to Candida albicans, a common yeast that can trigger allergic reactions. Elevated IgE may indicate sensitivity linked to respiratory, skin, or digestive symptoms. Physicians use this test to identify potential allergic responses, distinguish yeast-related immune activity, and guide evaluation of conditions affecting allergy, inflammation, or overall immune health.

The ACTH Test measures adrenocorticotropic hormone in blood to evaluate pituitary and adrenal gland function. Abnormal ACTH levels may indicate Cushing’s syndrome, Addison’s disease, adrenal tumors, or pituitary disorders. Doctors order this test to investigate symptoms such as fatigue, weight changes, weakness, or high blood pressure. Results provide vital insight into endocrine health, cortisol regulation, and adrenal-pituitary balance.

The Epstein-Barr Virus (EBV) Nuclear Antigen (EBNA) IgG Antibody Test detects IgG antibodies that usually appear after acute infection, confirming past exposure or infection recovery. Doctors order this test alongside VCA and EA antibodies to determine the stage of EBV infection. Results help distinguish recent versus past EBV, guide diagnosis of mononucleosis, and support evaluation of chronic fatigue or EBV-related health conditions.

The Hematocrit Test measures the percentage of red blood cells in blood, helping evaluate oxygen-carrying capacity and overall health. Abnormal results may indicate anemia, dehydration, polycythemia, or other blood disorders. Doctors use this test to investigate fatigue, weakness, or suspected blood loss and to monitor conditions affecting red cell production. Often performed with a CBC, it provides essential insight into blood and bone marrow function.

The Magnesium Serum Test measures magnesium levels in blood to evaluate electrolyte balance, nerve and muscle function, and overall metabolic health. Abnormal levels may indicate kidney disease, malnutrition, gastrointestinal disorders, or uncontrolled diabetes. Low magnesium can cause weakness, cramps, or irregular heartbeat, while high levels may signal kidney dysfunction. Doctors use this test to diagnose deficiencies, monitor therapy, or assess chronic health conditions.

The Pregnenolone Test measures pregnenolone levels in blood, a precursor hormone used to make cortisol, DHEA, estrogen, progesterone, and testosterone. Abnormal levels may indicate adrenal disorders, congenital adrenal hyperplasia, or pituitary problems. Doctors order this test to evaluate unexplained fatigue, infertility, or hormone imbalance and to monitor adrenal health. Results provide vital insight into endocrine function, steroid production, and overall hormonal balance.

The Vitamin B1 Plasma/Serum Test measures thiamine levels in blood to evaluate nutritional status and detect deficiencies. Thiamine is essential for energy metabolism, nerve function, and muscle health. Low levels may result from poor diet, alcoholism, malabsorption, or chronic illness and can lead to conditions like beriberi or Wernicke-Korsakoff syndrome. Doctors use this test to confirm deficiency and monitor supplementation or therapy effectiveness.

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 Complete Blood Count with Differential and Platelets Test is a comprehensive blood test that checks red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. The differential analyzes types of white blood cells to detect infections, anemia, clotting abnormalities, immune conditions, and certain cancers. This essential test is often ordered for routine health exams, diagnosis, and monitoring treatment progress.

The Hemoglobin and Hematocrit Test measures hemoglobin levels and the percentage of red blood cells in blood to assess oxygen-carrying capacity. Low values may indicate anemia, blood loss, or nutritional deficiencies, while high levels may suggest dehydration, lung disease, or polycythemia. Doctors use this test to investigate fatigue, weakness, or shortness of breath. Results provide vital insight into red blood cell health, oxygen delivery, and overall hematologic function.
