AB  - Thrombocytopenia in pregnant women is diagnosed frequently by obstetricians 
      because platelet counts are included with automated complete blood cell counts 
      (CBCs) obtained during routine prenatal screening (1). Although most U.S. health 
      care providers are trained using U.S. Conventional Units, most scientists, 
      journals, and countries use Systeme International (SI) units. The laboratory 
      results reported in U.S. Conventional Units can be converted to SI Units or vice 
      versa by using a conversion factor. The conversion factor for platelet count 
      results is 1.0 (ie, to convert from x 103/muL, multiply by 1.0, to get x 109/L). 
      Thrombocytopenia, defined as a platelet count of less than 150 x 109/L, is common 
      and occurs in 7-12% of pregnancies (2, 3). Thrombocytopenia can result from a 
      variety of physiologic or pathologic conditions, several of which are unique to 
      pregnancy. Some causes of thrombocytopenia are serious medical disorders that 
      have the potential for maternal and fetal morbidity. In contrast, other 
      conditions, such as gestational thrombocytopenia, are benign and pose no maternal 
      or fetal risks. Because of the increased recognition of maternal and fetal 
      thrombocytopenia, there are numerous controversies about obstetric management of 
      this condition. Clinicians must weigh the risks of maternal and fetal bleeding 
      complications against the costs and morbidity of diagnostic tests and invasive 
      interventions.
