Laboratory Findings
Laboratory Findings
- Complete blood count– Platelet counts may be low.
- Liver enzymes– Liver function tests (liver enzymes) may be high.
- Renal function and electrolytes
- Coagulation studies.
- Often, fibrin degradation products (FDPs) are determined, which can be elevated.
- Lactate dehydrogenase is a marker of hemolysis and is elevated (>600 U/liter).
- Proteinuria is present but can be mild.
- A positive D-dimer test in the presence of preeclampsia has recently been reported to be predictive of patients who will develop HELLP syndrome.[1] D-dimer is a more sensitive indicator of subclinical coagulpathy and may be a positive before coagulation studies are abnormal.
