Instructions
Recommended procedure for collecting sample without inducing hemolysis:
- An 18-gauge needle with attached infusion tubing is used.
- Place the tourniquet lightly around the upper arm. Puncture an antecubital vein with as little trauma as possible.
- Release the tourniquet and clamp the tubing off as soon as blood return is seen.
- First collect 3 mL blood in a red-top tube with the rubber top off.
- Then, collect 5 mL in an anticoagulated (heparin) tube with the top off.
- Clamp the tubing, withdraw the needle, and apply a pressure bandage to the site until residual bleeding is stopped.
- Recap the anticoagulant tube and gently mix three to five times.
- This specimen is used for the plasma hemoglobin determination.
- Centrifuge and separate plasma from red cells immediately following collection and transfer plasma to a transfer tube.
