title: [The usefulness of routine laboratory tests in the evaluation of sudden threat of pregnant woman and fetus in pre-eclampsia].
abstract: METHODS
  The fact that the progress of pre-eclampsia is highly unpredictable is the reason to run necessary monitoring, among others, by means of laboratory tests. Their aim is to determine explicitly if the pregnancy can be continued and terminated naturally or should be terminated by pre-term induced delivery or Caesarean section. There is a wide range of laboratory investigations recommended in pregnancy complicated by pre-eclampsia. The results reported in the literature though are controversial and inexplicit.
  
  
  OBJECTIVE
  The purpose of the research was to verify routine lab tests results used in decision making for emergency termination of pregnancy as a result of increased threatening clinical symptoms and to evaluate their usefulness in decision making to start delivery.
  
  
  METHODS
  The investigation covered 152 women who were divided into three groups. One consisted of 62 pregnant women with light form of pre-eclampsia, the other of 24 pregnant women with severe form of pre-eclampsia. The control group consisted of 66 healthy pregnant women. All pregnant women with pre-eclampsia diagnosed delivered by Caesarean section. The decision to perform the operation was based on biophysical findings of the fetus. At the moment of decision-making, blood was drawn for laboratory testing of the following parameters: systemic blood, coagulation parameters, total protein and protein fractios, non-protein nitrogen blood components, glucose, electrolytes, indicating enzymes and excretory enzymes of protein metabolism, lipid fractions.
  
  
  CONCLUSIONS
  Routine lab tests performed in pre-eclampsia do not indicate distinct abnormalities the moment fetus life threatening clinical symptoms occur that enforce the decision of immediate delivery, the exception are the indicating enzymes. Acute clinical symptoms that endanger fetus life in pre-eclampsia correlate with distinct activity of AspAT, AIAT and LDH. Laboratory tests are of no prognostic value in the prediction of sudden worsening of the fetus condition in pre-eclampsia.
