Investigation : Soluble Fms-Like Tyrosine Kinase-1
Specimen type : Serum_or_Serum_Gel
Spec container : Serum_or_Serum Gel 
Reference range : See below ng/L
Reference Intervals:

≤ 38, rule out pre-eclampsia for 1 week (week 24 to week 36 plus 6 days)

Clinical Interpretation

It defines pre-eclampsia as new-onset hypertension (over 140 mmHg systolic or over 90 mmHg diastolic) after 20 weeks of pregnancy plus 1 or more new-onset conditions. If a woman presents with some but not all of these criteria, they are considered to have suspected pre eclampsia. If they are under 37 weeks of pregnancy, this would be suspected preterm pre eclampsia.
