How do I convert Fibrin degradation products from mg/L to mg/dL?

mg/dL = mg/L × 0.1. In the other direction: mg/L = mg/dL × 10.

What is the reference range of Fibrin degradation products?

For adults the range is 0 – 10 mg/L (MedlinePlus (NLM): Fibrin degradation products blood test). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Fibrin degradation products?

Common units are mg/L, mg/dL, µg/dL, µg/L.

Fibrin degradation products unit converter

Breakdown products of fibrin (clot dissolution)

Also known as: FDP, Fibrin split products, FSP, Fibrin degradation product, Fibrinogen degradation products

Converter

Enter a value in any unit and all other units fill in.

mg/L = µg/mL mg/dL µg/dL µg/L

Worked example

5 mg/L (middle of the reference range) = 0.5 mg/dL

Conversion formulas

mg/dL	mg/dL = mg/L × 0.1	mg/L = mg/dL × 10
µg/dL	µg/dL = mg/L × 100	mg/L = µg/dL × 0.01
µg/L	µg/L = mg/L × 1000	mg/L = µg/L × 0.001

Good to know

Fibrin degradation products (FDP) are reported in µg/mL or mg/L, which are numerically identical.

1 µg/mL = 1 mg/L.
FDP and D-dimer are related but different tests with different ranges.

Reference range

Unit	Adults
mg/L = µg/mL	0 – 10
mg/dL	0 – 1
µg/dL	0 – 1000
µg/L	0 – 10 000
