Results help diagnose CMV, guide treatment, and assess risk of complications such as congenital infection or organ damage.

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 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 Hantavirus IgG IgM Antibodies Test with Reflex to Confirmation detects immune response to hantavirus infection. By measuring both IgM for recent infection and IgG for prior exposure, it aids in diagnosing hantavirus pulmonary syndrome (HPS) or hemorrhagic fever with renal syndrome (HFRS). Reflex confirmation ensures specificity, supporting evaluation of viral infection risk, disease progression, and immune status.

The Hepatitis A IgM Antibody Test is a qualitative blood test that detects IgM antibodies to the hepatitis A virus (HAV) and reports results as Reactive or Non-Reactive. A reactive result usually indicates a recent or current hepatitis A infection, while a non-reactive result means no active infection. Doctors use this test to confirm acute hepatitis A in patients with symptoms like jaundice, nausea, fatigue, or abdominal pain and to guide timely treatment and prevention.

The Hepatitis B Immunity Panel Test evaluates immune status by measuring Hepatitis B surface antibody levels in the blood. A positive result typically indicates immunity from vaccination or past infection, while a negative result suggests susceptibility. This test is important for verifying protection, monitoring vaccine response, or determining if additional vaccination or further evaluation for Hepatitis B exposure is needed.

The Hepatitis B Surface Antibody Qualitative Test detects anti-HBs antibodies to the hepatitis B surface antigen and reports results as Reactive or Non-Reactive. A reactive result indicates past exposure, either from hepatitis B infection or prior vaccination, while a non-reactive result suggests no detectable exposure. Doctors use this test to confirm hepatitis B exposure history, evaluate vaccine response, and guide further preventive or diagnostic decisions.

The Hepatitis B Surface Antibody Quantitative Test measures the exact level of anti-HBs antibodies in blood to determine past exposure and whether protective immunity has developed from infection or vaccination. A higher antibody level generally indicates adequate immune response, while a low level suggests limited or no protection. Doctors use this test to confirm vaccine effectiveness, assess immune status, and support hepatitis B screening or preventive care.

The Hepatitis B Surface Antigen (HBsAg) Test with Reflex to Confirmation screens for hepatitis B surface antigen in blood and, if reactive, automatically performs confirmatory testing.
