It is a test that detects antibodies against the Hepatitis B surface antigen (HBsAg) to assess immunity to Hepatitis B.

It is recommended after Hepatitis B vaccination, recovery from Hepatitis B, or as part of routine screening.

No special preparation is required. Inform your healthcare provider of any recent vaccinations or Hepatitis B history.

Results are usually available within 24 to 48 hours after the blood sample is collected.

Positive results indicate immunity to Hepatitis B, while negative results may suggest the need for further evaluation or vaccination.

Spirometry is a lung function test that measures how much air you can inhale and exhale, and how quickly you can do it.

Wear loose clothing, avoid heavy meals or intense exercise before the test, and follow any specific instructions from your doctor.

No, spirometry is non-invasive and painless. You will be asked to breathe into a device, which may feel slightly uncomfortable but is not painful.

The test itself takes about 15-30 minutes. Results are usually available immediately or within a few hours.

The frequency depends on your health conditions and doctor’s recommendations. It may be performed regularly for ongoing monitoring or as needed for diagnosis.
