Anti-HBs

Question 39

What disappears after a week or month when Anti-HBs appear?

Answer 39

HBsAg

Question 40

This is the amount of serum needed to provide protective immunity against HBV?

Answer 40

>10 mIU/mL of Serum

Question 41

(+) for IgM Anti-HAV?

Answer 41

Acute Hepatitis A

Question 42

(+) for Total Anti-HAV?

Answer 42

Recovery from Hepatitis A Includes the presence of IgG Anti-HAV, which leads to recovery

Question 43

(+) HBsAg, (+) Total Anti-HBc (+) IgM Anti-HBc (-) Anti-HBs

Answer 43

Acute Hepatitis B The presence IgM, HBsAg, and Total Anti-HBs but not Anti-HBs mean it is an acute infection (No IgG Anti-HBc)

Question 44

(-) HBsAg, (+) Total Anti-HBc (+) Anti-HBs

Answer 44

Recovery from Hepatitis B Anti-HBs is the marker for Immunity, so they're recovering by creating immunity.

Question 45

(+) HBsAg, (+) Total Anti-HBc (-) IgM Anti-HBc (-) Anti-HBs

Answer 45

Chronic Hepatitis B or Carrier No IgMs, so it's mostly IgGs, HBsAg means they are currenlty having an infection

Question 46

(-) HBsAg, (-) Anti-HBc (+) Anti-HBs

Answer 46

Immunity to Hepatitis B
