Specimen Collection:
SPECIMEN REQUIREMENTS Preferred sample: 200 uL non-hemolyzed plasma from a light green top tube. Send at ROOM TEMPERATURE. Alternate samples: 200 uL non-hemolyzed serum from a gold top tube. Send at ROOM TEMPERATURE. Minimum collection volume - 2 mL whole blood
Shipping and Handling Instructions:
SPECIMEN PROCESSING
Centrifuge at room temperature
SPECIMEN STABILITY
Whole blood stability at room temperature is 2 hours Plasma and serum stability as follows: Stable at room temperature for 7 days Can add on if plasma or serum has been kept at room temperature
TEST METHODOLOGY
Lactate and NAD are converted to pyruvate and NADH by LD. The rate of increase in NADH absorbance at 340 nm is directly proportional to the LD activity in the sample.
TESTING SCHEDULE
Performed as requested: 24 hours per day
SPECIAL INSTRUCTIONS
Keep plasma at room temperature until testing. DO NOT add on if sample has been refrigerated or frozen.
