A pregnant woman is sick with a rash, and her doctor is not sure if she has fifth disease (caused by parvovirus B19) or rubella (caused by rubella virus). The physician requests antibody titer tests. The results are: antiparvovirus B19 antibodies are primarily IgM, and antirubella virus antibodies are all IgA and IgG. (a) Which disease does the pregnant woman currently have? How do you know?
(b) Which disease has she had in the past? How do you know? (Points : 10)
Thank you for the opportunity to help you with your question!
he pregnant lady at present has fifth malady brought on by parvovirus B19. This is reason is IgM antibodies are the first antibodies delivered instantly after contamination. As the lady's immune response titer test uncovers that she has antiparvovirus B19 antibodies are fundamentally IgM, she is enduring with fifth infection.
She had rubella, in the past created by rubella infection. As she has antirubella antibodies, which are IgA and IgG; these antibodies are delivered to a great extent after optional introduction of the infection.
