Finding which of the following specific antibodies in a patient's blood would be most indicative of a very recent infection? Question 7 options: IgG IgM IgA IgE
Added by Timothy L.
Step 1
- IgG: This is the most common antibody in the blood and is responsible for long-term immunity. It is produced in response to infections and vaccines. - IgM: This is the first antibody produced in response to an infection. It is usually present in the blood early Show more…

4) A 26-year-old obstetric patient becomes ill during the first trimester of pregnancy with fever and lymphadenopathy. She is found to have a rising titer of anti- Toxoplasma gondii antibodies . She delivers a full- term baby with no apparent signs of in utero infection . The best test to diagnose acute infection in the neonate would be a parasite - specific ELISA for which isotype of immunoglobulin ? (A) IgA (B ) IgD (C) IgE (D) IgG (E) IgM
