It provides critical insight into abnormal protein production, disease activity, and treatment response.

The Protein Total and Protein Electrophoresis Test with Scan measures total protein in blood and separates it into albumin and globulin fractions to evaluate liver, kidney, and immune function. The scan identifies abnormal protein patterns linked to multiple myeloma, Waldenström’s macroglobulinemia, or chronic inflammation. Doctors order this test for unexplained fatigue, weight loss, or anemia. Results support diagnosis, monitoring, and treatment planning.

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 24-Hour Urine with Creatinine Test measures the amount of protein and creatinine excreted in urine over 24 hours. Elevated protein levels may indicate kidney disease, diabetic nephropathy, hypertension, or other renal disorders. Doctors use this test to evaluate kidney function, detect proteinuria, and monitor treatment response. Combining protein and creatinine helps ensure accurate results, making it essential for assessing long-term kidney health.

The Protein Total 24 Hour Urine Test measures total protein excreted in urine over a full day to evaluate kidney function and detect proteinuria. Elevated protein may indicate glomerular disease, nephrotic syndrome, diabetes, or hypertension-related damage. This test helps assess renal health, monitor progression of kidney disorders, and provide context for diagnosing systemic conditions affecting protein balance.

The PTH Intact Test measures intact parathyroid hormone (PTH) levels in blood to evaluate parathyroid gland function and calcium balance. Abnormal PTH may indicate hyperparathyroidism, hypoparathyroidism, kidney disease, or vitamin D imbalance. Doctors use this test to investigate osteoporosis, kidney stones, or unexplained calcium abnormalities. Results provide vital insight into endocrine function, bone metabolism, and overall calcium regulation.

The Red Kidney Bean f287 IgE Test measures IgE antibodies to proteins in red kidney beans. Elevated levels may indicate an allergic reaction, which can cause hives, itching, swelling, digestive discomfort, respiratory symptoms, or in severe cases, anaphylaxis. This test helps identify red kidney bean allergies and supports management through dietary avoidance and treatment strategies guided by healthcare providers.

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 Sedimentation Rate Blood Test, also called the Erythrocyte Sedimentation Rate (ESR) Test, measures how quickly red blood cells settle in a sample. A faster rate can signal inflammation linked to arthritis, autoimmune disease, or infection. Doctors order this test when patients have symptoms like joint pain, fever, or fatigue. While not diagnostic alone, results provide valuable insight into inflammatory activity and help guide further evaluation and treatment.

The Sjögren’s SS-A and SS-B Antibodies Test detects autoantibodies linked to Sjögren’s syndrome, an autoimmune disorder affecting tear and saliva glands.
