PlGF (Placental Growth Factor) Unit Converter
Placental Growth Factor (PlGF) is an angiogenic protein belonging to the VEGF family, produced primarily by the placenta. It is a key biomarker in obstetrics, particularly for the prediction and diagnosis of Preeclampsia.
In normal pregnancy, PlGF levels rise during the first two trimesters and decrease as term approaches. In preeclampsia, PlGF levels are abnormally low. It is often analyzed in conjunction with **sFlt-1** (soluble fms-like tyrosine kinase-1) to calculate the sFlt-1/PlGF ratio. This converter facilitates switching between common mass units used in clinical assays.
Standard Mass Units
Most CommonPicograms per milliliter (Numerically equivalent to ng/L).
Other Equivalents
Clinical Context
Reference Values: PlGF levels vary significantly by gestational age. Always refer to your laboratory’s trimester-specific ranges.
Preeclampsia Screening:
• Low PlGF: Indicates placental dysfunction.
• sFlt-1/PlGF Ratio: Used to rule out preeclampsia in the short term (e.g., within 1 week). A low ratio predicts the absence of preeclampsia.
Conversion Logic:
1 pg/mL = 1 ng/L.
1,000 pg/mL = 1 ng/mL.

Frequently Asked Questions
Yes. 1 picogram per milliliter is numerically identical to 1 nanogram per liter.
The ratio of sFlt-1 (anti-angiogenic) to PlGF (angiogenic) reflects the balance of placental health. An elevated ratio suggests placental insufficiency.
