c
HBeAb
QuestionChoice
No, this is the incorrect answer. Immunoglobulin M (IgM) is an antibody produced by the body as part of the response to infection. It does not indicate the patient is highly infectious with regard to their hepatitis B.

e
IgM (core antibody)
QuestionChoice
Yes, this is the correct answer. HBeAg is the e-antigen of the hepatitis B virus. It is produced by the hepatitis B virus, and indicates active viral replication. Thus, raised levels in the bloodstream indicate a highly infectious state.

a
HBeAg
QuestionChoice
No, this is the incorrect answer. HBsAg, or the hepatitis B virus surface antigen, is the first antigen to be elevated in the bloodstream following an infection. It is responsible for the initial rises in ALT levels but does not indicate a highly infective state.

QuestionChoice
No, this is the incorrect answer. This is the hepatitis B surface antibody. This is one of the last antibodies to appear serologically, which indicates the clearance of the hepatitis B virus and hence recovery.

A 45-year-old man presents to his GP surgery with jaundice. He is noted to have abnormal liver function tests (LFTs)


||||
|---------------------------|:-------:|--------------------|
|Bilirubin|74 µmol/L|< 17|
|Alanine Aminotransferase (ALT)|2835 IU/L|10 - 50|
|Alkaline Phosphatase (ALP)|155 IU/L|25 - 115|


The LFT results suggest hepatic causes of jaundice. After further serology testing, a diagnosis of hepatitis B is made.


Which of the following positive result on serology would suggest a highly infective state for this patient?
a
