1

Diagnosis of an active Hep A virus

IgM-HAV antibody

2

Diagnosis of Hep B

HBs Ag (surface)
HBc Ag (core)

3

Diagnosis of Hep C

IgG-HCV antibody
HCV RNA - shown 1-2 weeks after infection

4

HBs Ag for >6months

Chronic Hep B

5

Antigens of a person naturally infected by Hep B

HBs Ag
HBc Ag

6

Antibodies of a person who is vaccinated against Hep B

IgG-HBs antibody

7

Antigens of a person infected with Hep B that is highly infectious

HepBe Ag
HBV DNA

8

What antigens is found in all Hep B individuals

HBs Ag

9

Presence of HCV Antigen

A past or currently active infection of Hep C

10

Presence of HCV RNA

A currently active infection

11

What is the best indicator for prognosis in Hep B?

HBV DNA

12

Diagnosis of Type 1 Autoimmune Hep

Anti-nuclear antibody (ANA)
Anti-smooth-muscle antibody (ASMA)

13

Diagnosis of Type 2 Autoimmune Hep

Anti-LKM-1
Anti-LCM-1

14

What are the 3 antigens of Hep B

HBs Ag (surface)
HBe Ag (envelope)
HBc Ag (core)

15

Memory aid for HBs Ag

It is the bad-boy antigen, your body wants to get rid of it as it carries with it the most symptoms.

The more HBs Ag the worse your symptoms

16

HBe Ag

This antigen is responsible for replicating the virus in your blood.

The more HBe Ag the easier it is to transmit

17

Antibody in someone that has recovered or been vaccinated for Hep A

IgG-HAV antibody

18

Decrease in HCV RNA

Patient is recovering

19

Levels of HCV RNA staying the same

Patient has chronic HCV

20

Presence of IgG-HDV and IgM-HDV antibodies

Active infection
