Hexokinase, NADH Endpoint
Determine glucose level, monitor insulin therapy, evaluate carbohydrate metabolism.
Fasting: <1 year: 40 - 120 mg/dL, 1-4 years: 50 - 130 mg/dL, 5-11 years: 50 - 135 mg/dL, 12-150 years: 73 - 100 mg/dL.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
- Lactose Tolerance Test
- GLUCOSE LEVEL
- RBS (random blood sugar)
STAT requests for this test will be performed on a STAT basis (supervisory staff approval is not required).
Collect specimen in an SST tube depending on the measurement requested (random, fasting, 1 hour postprandial or 2 hour postprandial). Centrifuge within 4 hours of collection, aliquot serum into a plastic vial and refrigerate. If specimen cannot be centrifuged at client site, please arrange for delivery to MLabs within 3 hours of specimen collection.
If fasting specimen desired, patient should be fasting prior to collection.
Falsely elevated potassium levels or falsely decreased glucose levels may result when the specimen remains uncentrifuged for more than 4 hours after collection. MLabs requests that samples for potassium and/or glucose collected at the client site be centrifuged or delivered uncentrifuged within 3 hours of collection. If unspun specimens sent for potassium or glucose testing are received without a collection date and time noted, MLabs will make every effort to obtain this information from the client. The specimen will not be rejected for being uncentrifuged; however, the following comment will be added to the report: "Specimen was received uncentrifuged more than four hours after draw. This may cause falsely elevated potassium level or falsely decreased glucose level. Please interpret results accordingly."
