Description
ONA vacuum blood collection tubes contain sodium citrate (3.2% or 3.8%) and are specifically designed for coagulation testing. They ensure a precisely controlled blood-to-additive ratio for accurate measurement of plasma coagulation parameters. Ideal for routine and specialized assays such as PT, APTT, and INR, they are fully compatible with standard laboratory analyzers.
Key features
- Blood-to-additive ratio 9:1 or 4:1.
- Compatible with centrifugation at 2000–2500 g for 10–15 minutes.
- Manufactured from medical-grade PET/Glass.
Applications
Coagulation tests, PT, APTT, ESR.
