Patient should discontinue taking Biotin, Vitamin B7, or Vitamin H 48 hours before getting blood drawn.
* This volume does not allow for repeat testing
Specimens must be filled appropriately see this example
Correct ratio of Blood to Citrate is critical (9:1). Specimens must be filled within +/- 10% of stated volume.
If a Blue Top Tube is collected utilizing a butterfly, a Blue Discard Tube must be drawn first to remove air from the line. If this is not done, the Blue Top Tube will not be filled properly due to the vacuum in tube and a redraw will be required
Note:
Collection of blood for coagulation testing through intravenous lines that have been previously flushed with heparin should be avoided, if possible.
If the blood must be drawn through an indwelling catheter, possible heparin contamination and specimen dilution should be considered.
When obtaining specimen from indwelling lines that may contain heparin, the line should be flushed with 5 mL of saline, and the first 5 mL of blood or 6-times the line volume (dead space volume of the catheter) be drawn off and discarded before the coagulation tube is filled. For those samples collected from a normal saline lock (capped off venous port), twice the dead space volume of the catheter and extension set should be discarded.
Heparinized Patient specimens must be spun within 1 hour of collection - Follow Platelet Poor Plasma preparation instructions
Clotted samples
Improperly filled tubes (under or overfilled)
Wrong anticoagulant (3.8% sodium citrate is NOT acceptable)
Patients with hematocrit (HCT) >55% (red cell volume is >1/2 tube volume)
Hemolyzed samples
Whole blood that was refrigerated or placed on ice
DO NOT freeze in a frost-free freezer
Frozen samples that were thawed in transport, or thawed samples that were refrozen
This tube must be transported to testing laboratory within 45 minutes from collection.
If this is not possible, follow these steps:
1. Heparinized patient specimens must be spun within 1 hour of collection, following these Platelet Poor Plasma preparation instructions
2. Send the platelet poor plasma and primary tube to the testing laboratory
3. Contact the laboratory at 266-1500 (Option 1) to notify PRMC laboratory that the specimen is coming
Avoid Hemolysis
Centrifuge and separate from cells within 4 hours of collection
* This volume does not allow for repeat testing
Mix tube by inversion 5 times
Do not centrifuge
Specimens must not be clotted. Overfilling or underfilling may allow blood to clot. Specimens may be rejected due to improper storage or age of specimen

Patients taking vitamin supplements containing doses of > 5 mg/day may have falsely decreased test results generated.
