Grossly lcteric
Clotting

2- If the samples is grossly lipemic after centrifugate it
3- you received a sample was collected on a non-sodium citrate anticoagulant
The corrective actions
1- The sample must be rejected and another sample will be requested.
2- Centrifuge the sample again, if it still lipemic reject this sample and another sample will be requested
