Interferences and Limitations

Cautions:

Results must always be interpreted together with other clinical and laboratory findings.

Serum specimens drawn during the acute phase of infection may be negative by serological tests.

All positive results must be interpreted with care, as some false-positive results or heterotypical responses of the IgM have been seen in the serum of pregnant women or in patients with an acute infection caused by cytomegalovirus, herpes simplex virus, measles, rubella, and parvovirus.
