Hepatitis B Antibody (HBcAb) Blood Test – current infection

This test checks for the presence of antibodies called IGM in your blood, which indicates whether you are currently infected with hepatitis B. The IGM antibodies are the first antibodies produced after an infection. Hepatitis B can cause serious liver damage, and is transmitted through unprotected sex, sharing needles or from any situation where you come into contact with bodily fluids from an infected person.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
