| Collection Instructions |
Avoid hemolysis. Falsely low results may be caused in patients treated with N-Acetyl Cysteine (NAC) or Metamizole (Dipyrone). |
| Specimen Instructions |
Allow serum samples to clot completely before centrifugation. Serum gel tubes should be centrifuged within 2 hours of collection. Red-top tubes should be centrifuged and aliquoted to a plastic transport tube within 2 hours of collection. Avoid hemolysis. Gel tubes should be spun at room temperature at a speed of 1000 to 1300 RCF for 10 minutes in a swinging bucket centrifuge and 15 minutes in a fixed-angle centrifuge. non-gel serum tubes can be centrifuged at ≤ 1300 RCF for 10 minutes. After centrifugation refrigerates the samples at 2 to 8°C. |
| Reasons for Rejection |
