2nd order laboratory parameters – depending on the results of the medical history, physical examination, etc. – for differential diagnostic clarification
- Parvovirus B19 antibodies (IgM and IgG; if IgG antibodies are detectable but no IgM antibodies, there is immune protection; IgM antibodies are detectable seven to ten days after infection and remain positive for up to three months).
- Small blood count
- Toxoplasmosis antibodies (IgG, IgM)
- TPHA search test
- Measles antibodies (IgG, IgM)
- Rubella antibodies (IgG. IgM)
Notice.
Infection with parvovirus in the second trimester (third of pregnancy) may cause an increase in the concentration of alpha-1 fetoprotein!
Caution.
If a pregnant woman has no immune protection against ringworm, a new blood test after 2 weeks is absolutely necessary to exclude a possible ringworm infection.
To detect infection in a pregnant woman, amniocentesis can be performed from the 16th week of pregnancy.
