LACTATE P

Ordering Recommendation

New York DOH Approval Status

This test is New York state approved.

Specimen Required

Patient Preparation

Patient should be fasting and at complete rest and avoid any exercise of the arm or hand before or during collection. Avoid hand clenching and draw the specimen without the use of a tourniquet if possible. A tourniquet with patient clenching and unclenching hand will lead to high potassium and lactic acid buildup from the hand muscles, and pH will decrease.

Collect

Gray (potassium oxalate/sodium fluoride) prechilled in ice bath. Collect blood without stasis.

Specimen Preparation

Mix well by gentle inversion then return to ice bath. Separate from cells within 15 minutes and transfer 1 mL plasma to an ARUP standard transport tube. (Min: 0.5 mL)
Test is not performed at ARUP; separate specimens must be submitted when multiple tests are ordered.
