Doctors order this test to confirm gluten intolerance, support diagnosis of celiac disease, and monitor adherence to a gluten-free diet.
Tissue Transglutaminase IgG Antibody Test, Anti-tTG IgG Test
The Cytomegalovirus (CMV) IgM Antibody Test detects IgM antibodies, indicating a recent or active CMV infection. This blood test helps diagnose primary CMV, reactivation, or reinfection, especially important for pregnant women, transplant candidates, and immunocompromised patients. Used with CMV IgG testing, it helps distinguish new infections from past exposure for accurate clinical evaluation.
The Cytomegalovirus (CMV) IgG Antibody Test detects IgG antibodies to CMV, indicating past infection or immunity. This blood test helps determine prior exposure, assess immune status in pregnancy, transplant patients, or immunocompromised individuals, and guide risk evaluation. A positive result shows past CMV infection, while results are used with IgM testing to distinguish recent vs. past infection.
The Parietal Cell Antibody Test detects autoantibodies against stomach parietal cells, which produce intrinsic factor and stomach acid. Their presence is strongly associated with pernicious anemia, vitamin B12 deficiency, and autoimmune gastritis. Doctors use this blood test to help diagnose the cause of anemia, investigate digestive issues, and evaluate patients with suspected autoimmune disorders affecting stomach function and nutrient absorption.
The Actin Smooth Muscle IgG Antibody Test detects autoantibodies against smooth muscle actin, often linked to autoimmune hepatitis and chronic liver disease. Elevated levels may indicate liver inflammation, cirrhosis, or other autoimmune conditions. Doctors use this blood test with liver panels and additional antibody tests to aid in diagnosis, monitor disease progression, and guide treatment decisions for patients with suspected autoimmune liver disorders.
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 Toxoplasma IgG Antibody Test detects IgG antibodies to Toxoplasma gondii, the parasite that causes toxoplasmosis. A positive result indicates past infection or immunity, while rising levels may suggest recent exposure. Doctors use this blood test to evaluate immune status in pregnant women, immunocompromised patients, or those at risk for complications. Results help guide diagnosis, monitor infection history, and inform patient care planning.
The Hepatitis Be Antibody (anti-HBe) Test is a qualitative blood test that detects antibodies to the hepatitis B e antigen and reports results as Reactive or Non-Reactive. A reactive result often indicates lower infectivity and a transition toward recovery or inactive disease, while a non-reactive result suggests no antibodies were detected. Doctors use this test to monitor hepatitis B infection stage, evaluate treatment response, and support long-term disease management.
The T3 Antibody Test measures antibodies directed against triiodothyronine (T3), an essential thyroid hormone. The presence of T3 antibodies can interfere with thyroid hormone assays and may indicate autoimmune thyroid disorders such as Hashimoto’s thyroiditis or Graves’ disease. This test provides insight into abnormal thyroid function, autoimmunity, and diagnostic evaluation of unexplained thyroid test results.
The 14 Serotypes Streptococcus Pneumoniae IgG Antibody Panel evaluates IgG antibodies to key pneumococcal serotypes linked to invasive infections.
