The Hepatitis B Core Antibody Test detects antibodies against the core antigen of Hepatitis B virus, indicating past or current infection.

The test is used to diagnose Hepatitis B infection, assess immune response, and guide further testing.

No special preparation is needed. You can eat and drink normally. Inform your healthcare provider about any medications or recent health issues.

Results are typically available within 1 to 2 days after the test.

A positive result indicates past or current exposure to Hepatitis B virus. It may require further testing to determine the infection stage and appropriate management.

Risks may include infection, nerve or blood vessel damage, joint stiffness, and complications related to the limb lengthening device.

The Serum Renin Test measures renin levels to assess kidney function and diagnose conditions related to blood pressure regulation and adrenal function.

You may need to avoid certain foods, activities, or medications before the test. Follow specific instructions from your healthcare provider for accurate results.

The test is often performed in the morning, as renin levels can vary throughout the day. Timing instructions will be provided by your healthcare provider.

Elevated or decreased renin levels can indicate conditions such as secondary hypertension, kidney disorders, or adrenal dysfunction. Further evaluation may be needed.

Results are generally available within 24 to 48 hours after the blood sample is collected, allowing for prompt review and diagnosis.
