Study Notes

When the mother is Rh-negative and the father is Rh-positive, there is a risk of hemolytic disease in the fetus or newborn, as the mother's immune system may react to the Rh-positive fetal blood cells.

A detection limit of 6 mg/L of CRP in the patient's serum means that the test can detect CRP levels above 6 mg/L, indicating the presence of inflammation or infection in the body.
The main cause of increased CRP in the body is the presence of inflammation or infection, which triggers the liver to produce more CRP.

When latex particles coated with antibodies to human CRP are mixed with serum containing elevated CRP levels on a slide, agglutination (clumping) occurs, visually indicating the presence of CRP in the serum.

A positive result for ASO indicates that the individual has had a recent or past streptococcal infection, such as strep throat.
The main purpose of measuring the amount of ASO in the blood is to diagnose and monitor the progression of streptococcal infections, particularly rheumatic fever.

When a fetus inherits the Rh factor from the father, the mother's immune system may react to the Rh-positive fetal blood cells, causing hemolytic disease in the fetus or newborn.
