Blood samples
| Test Required | Sample Required | Comments |
|---|---|---|
| Haematology | EDTA | Mix gently immediately after collection |
| Biochemistry | Serum | Centrifuge after permitting sufficient clotting time (min 2 hours) |
| Fibrinogen | Citrate | Mix gently immediately after collection |
| SAA | Serum | Needs to be processed quickly as the half life is very short |
| Electrolytes | Heparin | Mix gently immediately after collection |
| Glucose | Fluoride oxalate | Can use fresh whole blood if tested immediately |
| Insulin | Serum | Fasting sample required |
| Prothrombin clotting time | Citrate | A normal sample is required for comparison |
| Progesterone | Serum | |
| Oestrone Sulphate | Serum | |
| Testosterone | Serum | Request Testosterone before Inhibin for GCTs |
| IgG | Serum | Measurement techniques vary so check sample requirements |
| ACTH | EDTA plasma | Freeze plasma as soon after collection as poss (max 2 hours) |
| Selenium | ||
| Zinc | Serum | Avoid using tubes with a rubber bung |
| Drugs testing | Serum or Heparin | Send to HFL |
| Virus Titres e.g. EHV | Serum | Take 2 samples 14 days apart (freeze 1st) |
| Tapeworm ELISA | Serum |
