What is GTT on a lab?
lab that determines if high alk phos is from liver or the bone
Acute or chronic? Hep A
Acute and goes away in 3 months. Hepatitis A: DOES NOT CAUSE CHRONIC LIVER DISEASE!

The first thing that will appear in the blood when you are sick with Hep B, will persist throughout sickness.
Having Hep B Surface Antigen for > 4 means:
Chronic Hep B
Chronic Hep B is defined as:
having Hep B Surface Antigen in blood for > 4 months
What is Anti Hep B surface antigen?
the antigen to HBsAg. Only appears when you have cleared the disease. You don’t have HBsAg anymore. Only Anti HBs.
If you’re vaccinated you will have __ in the blood. You won’t have ___ in blood.
you will have Anti HBs
you won’t have HBsAg
Why should you test for Hep B core antibody when testing for Hep B?
It fills the window period between HBsAg and Anti HBs.
Having what in blood means you were vaccinated for Hep B?
IgG
What is found in the blood in only only in very infectious/unlucky cases of Hep B? Indicates viral replication and infectivity
HBeAg - Hep B ‘E’ Antigen
