Frequently Asked Questions
What types of blood bottles do you offer?
▼
We stock a wide range of blood bottles, including plain, EDTA, citrate, and gel separator tubes. Each type is colour-coded for easy identification and specific diagnostic use. Common UK blood bottle colour codes include:
- Purple (EDTA): Used for full blood count (FBC), ESR, and blood films. Contains EDTA, which prevents clotting.
- Blue (Citrate): Used for coagulation tests like PT and INR. Contains sodium citrate as an anticoagulant.
- Yellow (SST/Clot Activator): Used for biochemistry tests (such as U&E, LFTs, CRP). Contains gel to separate serum after centrifugation.
- Grey (Fluoride Oxalate): Used for glucose and lactate tests. Contains fluoride to inhibit glycolysis.
- Pink (EDTA - crossmatch): Similar to purple but typically used for blood group and crossmatch.
- Green (Heparin): Used for certain specialist biochemistry tests. Contains lithium or sodium heparin.
That being said, always refer to your local trust or lab guidelines, as protocols may vary slightly.
