1st order laboratory parameters – obligatory laboratory tests.
- Small blood count
- Differential blood count
- CRP (C-reactive protein) – inflammatory parameter.
- ESR (erythrocyte sedimentation rate) – inflammatory parameter.
- Direct microscopic detection of the pathogen in the blood.
- Toxoplasma gondii antibody detection (IgM/IgG detection in immunofluorescence).
Pregnant women should be reassayed serologically 14 days after a positive IgM test.
Laboratory parameters 2nd order – depending on the results of the history, physical examination, etc. – for differential diagnostic clarification.
- Toxoplasma gondii DNA detection.
- Gamma-GT (gamma-glutamyl transferase), ALT (alanine aminotransferase; GPT), AST (aspartate aminotransferase; GOT), GLDH (glutamate dehydrogenase), alkaline phosphatase, bilirubin – for liver function.
- Creatinine, urea, uric acid – because of renal function.
- CSF examination in the case of involvement of the central nervous system.
- TPHA search test in suspected syphilis (lues).
- HIV antibody screening test
- EBV antibody test for suspected Epstein-Barr infection.
- Rubella antibody test
- Tuberculin test or test for acid-fast rods in suspected tuberculosis.
- Blood tests for pathogens such as histoplasmosis, herpes simplex virus or varicella zoster virus.
