HbsAg By Rapid

You should get an HBsAg rapid test when quick screening for hepatitis B is needed, such as before surgery, during labor or emergency admission, before blood donation, or in screening camps. It is also useful if you have jaundice, fatigue, or abdominal pain, or possible exposure, with lab confirmation of positive results.

No special preparation or fasting is required for an HBsAg rapid test. A small blood sample from a finger prick or vein is used. Inform your doctor if you received a hepatitis B vaccine in the past 2–3 weeks, or about any recent exposure. If you test positive, a confirmatory lab test will be needed.

No, fasting is not required for an HBsAg rapid test. You can eat and drink normally before the test, and it can be done at any time of day. Results are usually available within 15–20 minutes. A positive result should be confirmed with a laboratory test such as CLIA or CMIA.
