All Inflammation Tests

The Myeloperoxidase (MPO) Antibody Test detects autoantibodies against MPO, often associated with ANCA-associated vasculitis, including microscopic polyangiitis and granulomatosis with polyangiitis. Elevated MPO antibodies may indicate inflammation of blood vessels, kidneys, or lungs. Physicians order this blood test to support diagnosis, monitor disease activity, and guide treatment decisions for autoimmune and systemic vasculitis disorders.

The Pancreatic Elastase-1 Test measures elastase enzyme levels in stool to evaluate pancreatic exocrine function. Low elastase indicates pancreatic insufficiency, which may result from chronic pancreatitis, cystic fibrosis, or pancreatic cancer. By assessing enzyme activity in digestion, this test provides valuable insight into malabsorption, gastrointestinal symptoms, and overall digestive health.

The Phosphate (as Phosphorus) Test measures phosphorus levels in blood to evaluate bone strength, energy metabolism, and kidney health. Abnormal levels may indicate kidney disease, vitamin D imbalance, parathyroid disorders, or malnutrition. Doctors order this test to investigate fatigue, muscle weakness, or bone problems and to monitor conditions like chronic kidney disease. It provides key insight into metabolic, endocrine, and bone health.

The Prealbumin Test measures levels of prealbumin, a protein made by the liver that reflects short-term nutritional status. Low levels may indicate malnutrition, liver disease, inflammation, or chronic illness, while high levels may be linked to kidney disease or steroid use. Doctors use this test to assess protein-calorie nutrition, monitor patients receiving nutritional support, and guide treatment for conditions affecting metabolism and recovery.

The Protein Total 12 Hour Urine with Creatinine Test evaluates protein and creatinine levels in timed urine collection to help detect kidney damage, filtration disorders, and systemic conditions. Elevated protein may indicate nephrotic syndrome, chronic kidney disease, or diabetes-related renal complications. This test aids in assessing kidney function, protein balance, and overall metabolic health.

The Protein Total Serum Test evaluates total protein concentration, reflecting both albumin and globulin, which play key roles in immune response, liver function, and nutrient transport. Abnormal findings may signal malnutrition, kidney or liver disease, or chronic inflammatory conditions. This test aids in assessing protein metabolism, systemic health, and overall physiological balance.

The Proteinase-3 Antibody Test detects antibodies against proteinase-3, a neutrophil enzyme associated with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Elevated levels are strongly linked to granulomatosis with polyangiitis and other autoimmune small vessel vasculitides. This test aids in diagnosis, assessing disease activity, and guiding management of systemic inflammatory and autoimmune vascular conditions.

The Rheumatoid Factor (RF) Test measures RF antibodies in blood to help diagnose rheumatoid arthritis and other autoimmune conditions. High RF levels may indicate rheumatoid arthritis, Sjögren’s syndrome, or other connective tissue diseases, though they can also appear in some infections. Doctors order this test to investigate joint pain, stiffness, or swelling. Results provide important insight into autoimmune activity, joint health, and inflammatory disease management.

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 Sed Rate Test, also called the ESR Test, measures how quickly red blood cells settle in a sample of blood. A faster rate may signal inflammation caused by infections, autoimmune diseases, arthritis, or other chronic conditions. Doctors use this test to investigate unexplained fever, joint pain, or muscle aches, and to monitor inflammatory disorders such as lupus or rheumatoid arthritis. The Sed Rate Test provides important insight into overall inflammatory activity.

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 Theophylline Test measures blood levels of theophylline, a bronchodilator used to manage asthma, COPD, and chronic bronchitis. Monitoring levels ensures therapeutic effectiveness while reducing risks of toxicity, which can cause nausea, arrhythmias, or seizures. This test supports dosage adjustment, evaluates drug interactions, and guides long-term management of respiratory disorders requiring theophylline therapy.

The Thyroid Peroxidase Antibodies (TPOAb) Test detects antibodies that target thyroid peroxidase, an enzyme vital for thyroid hormone production. High levels often indicate autoimmune thyroid disorders such as Hashimoto’s thyroiditis or Graves’ disease. Doctors order this test to evaluate symptoms like fatigue, weight changes, hair loss, or irregular heartbeat and to confirm thyroid disease. It provides key insight into autoimmune activity and overall thyroid 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 Uric Acid Test measures uric acid levels in blood to assess kidney function and detect gout, a form of arthritis caused by uric acid buildup. High levels may also signal kidney disease, kidney stones, or metabolic disorders, while low levels can occur with liver disease. Doctors use this test to investigate joint pain, swelling, or frequent urination, and to monitor treatment for gout, kidney stones, or chemotherapy-related complications.

The Urinalysis Complete Test evaluates urine for physical, chemical, and microscopic properties to assess kidney health, urinary tract infections, diabetes, and metabolic disorders. It measures appearance, concentration, pH, protein, glucose, ketones, blood, bilirubin, nitrites, leukocyte esterase, and microscopic cells or crystals. Doctors use this test in routine exams, to diagnose urinary symptoms, and to monitor chronic kidney or metabolic disease.

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 QuestAssureD™ Vitamin D 25-Hydroxy Total Test measures Vitamin D2, Vitamin D3, and total 25-hydroxy vitamin D to assess overall vitamin D status. Adequate vitamin D supports bone strength, calcium absorption, immune health, and muscle function. Low levels may cause osteoporosis, weakness, or increased disease risk, while high levels can indicate toxicity. Doctors use this test to diagnose deficiency, monitor supplementation, and evaluate metabolic and endocrine health.
