This essential test is often ordered for routine health exams, diagnosis, and monitoring treatment progress.

The Cystatin C Test with eGFR measures blood levels of Cystatin C, a protein filtered by the kidneys, and calculates estimated glomerular filtration rate (eGFR). This test provides a sensitive marker for kidney function and can detect early kidney disease, even when creatinine levels are normal. Doctors order it to evaluate chronic kidney disease risk, monitor treatment, and assess overall kidney health in patients with diabetes, hypertension, or other conditions.

The DNA (ds) Antibody Test detects double-stranded DNA antibodies, often linked to systemic lupus erythematosus (SLE) and other autoimmune diseases. High levels may indicate lupus activity, kidney involvement, or autoimmune flare-ups. Doctors order this test for patients with joint pain, fatigue, rash, or suspected connective tissue disease. Results provide critical insight for diagnosing lupus, monitoring disease progression, and guiding treatment decisions.

The Early Sjögren’s Syndrome Profile tests for antibodies to carbonic anhydrase VI (CA VI), salivary protein 1 (SP-1), and parotid specific protein (PSP) across IgG, IgA, and IgM isotypes. These novel biomarkers may appear before classic SS-A/SS-B antibodies, helping identify Sjögren’s syndrome earlier. This profile supports assessment of early autoimmune damage to salivary and lacrimal glands.

The Erythropoietin (EPO) Test measures levels of erythropoietin, a hormone made by the kidneys that stimulates red blood cell production. Abnormal levels may indicate anemia, chronic kidney disease, or bone marrow disorders. Elevated EPO can also occur with low oxygen levels or tumors. Doctors order this test for patients with unexplained fatigue, shortness of breath, or abnormal blood counts. Results help guide diagnosis, treatment, and monitoring of anemia-related conditions.

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 Galectin-3 Test measures levels of galectin-3, a biomarker linked to heart failure, cardiac fibrosis, and inflammation. Elevated results may indicate worsening heart disease, increased risk of hospitalization, or progression of chronic conditions. Doctors use this blood test to assess heart health, guide treatment decisions, and monitor patients with heart failure, offering valuable insight into long-term cardiovascular risk and management.

The General Hepatitis Panel Test screens for multiple hepatitis infections in one order. It includes Hepatitis A Antibody Total, Hepatitis B Surface Antibody Qualitative, Hepatitis B Surface Antigen with Reflex to Confirmation, Hepatitis B Core Antibody Total, and Hepatitis C Antibody with Reflex to RNA PCR. Doctors use this panel to detect past exposure, confirm active or chronic infection, guide treatment, and support liver health monitoring.

The HLA DRB1 DQB1 Low Resolution Test determines genetic variations within the HLA class II region, specifically DRB1 and DQB1 alleles. These markers play an important role in immune system regulation and are associated with autoimmune conditions such as type 1 diabetes, celiac disease, and rheumatoid arthritis. This test provides insight into genetic predisposition, transplant matching, and immune-related disease risk.

The HLA-B27 Antigen Test detects the presence of the HLA-B27 protein on white blood cells, which is linked to autoimmune conditions. A positive result may indicate higher risk for ankylosing spondylitis, reactive arthritis, or other spondyloarthropathies.
