Key facts

• Soluble fms-like tyrosine kinase-1/placental growth factor [Ratio] in Serum
• Soluble fms-like tyrosine kinase-1/placental growth factor
• sFlt-1 levels are higher and PIGF levels lower in women that develop preeclampsia than women with a normal pregnancy. The sFlt-1/PIGF ratio may be a better indicator of preeclampsia than either value by itself. This term is based on, but not limited in use to, the Elecsys PIGF (Human placental growth factor) and sFlt-1 assays.
