Brief Summary:
Establishment of a range of normal values in pregnancy with the Multiple Electrode Aggregometry (Multiplate@) device, a device that allows measurement of not only platelet count but platelet function. This has not been studied in ths special patient group. Results from this trial will be used as a basis for further investigation of abnormal platelet function in pregnancy.

Estimated Study Completion Date : May 2015

Intervention Details:
  • Other: Platelet function during pregnancy Multiple Electrode Aggregometry (Multiplate@) device
    Observation of platelet function in pregnancy

Primary Outcome Measures :
  1. Change of platelet function [ Time Frame: 4x, as specified below ]

    Measurement of change of platelet function by the Multiplate® device. First measurement (baseline measurement) at enrollment into the trial. Second measurement during government-mandated gynaecological evaluation, around the 20th week of pregnancy.

    Third measurement immediately prior to delivery. Last measurement one week after delivery. 2nd, 3rd and 4th measurement for assessment of change from baseline.

Secondary Outcome Measures :
  1. Platelet-associated complications [ Time Frame: 4x, as specified below (baseline, 20th week) ]

    Record of bleeding events, preeclampsia, HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome.

    Time points: at every assessment of primary outcome measure, as described above.
