11600 = Lactic Acid and 11610 = Lactic Acid Reflex
2.0 ml Gray – Sodium Fluoride Potassium Oxalate Plasma
Draw to dark line on tube, 2.0 ml. Place on ice after collection, Centrifuge for 5 minutes, separate from contact with cells within 15 minutes of collection.
1 ml plasma Min: 0.5 ml
Plasma should be physically separated from contact with cells within 15 minutes of sample collection and analyzed without delay. If sample cannot be tested immediately after centrifuging, pipet plasma from the cells, place in a tube with a cap, cap tightly, refrigerate up to 14 days. FOR CSF samples only, samples are stable stored at 2-8 degree Celsius for up to 24 hours. IF Lactic Acid Reflex is greater than or equal to 2.0 mmol/L, then another Lactic Acid will automatically be ordered for collection 3 hours later.
Specimen Processing Instructions
Plasma: Centrifuge at 3380 rpm’s (±100) for a minimum of 5 minutes
Separate from contact with cells within 15 minutes of sample collection and analyzed without delay.
On Ice or in an ice pack
0.3 – 2.1 mmol/L
Greater than 4.0 mmol/L
Measuring the absorbance due to the chromophore using an endpoint technique
Daily, Monday - Sunday
If Lactic Acid Reflex is ordered, if the results are greater than or equal to 2.0, our LIS will automatically order a Lactic Acid to be collected 3 hours after the collection time.
