NEW TEST CODES FOR GLUCOSE TOLERANCE PANELS

 

Effective January 8, 2025, the MLabs Chemistry Clinical Core Laboratory will introduce new oral glucose tolerance panels and update existing ones as follows. These changes are designed to enhance clarity for providers and allow all abnormal values to be flagged, in addition to providing explanatory test message comments.     

 

Order codes GLU2P (Glucose Level, 2 Hr Postprand.) and GLUC3 (Glucose Tolerance, 3 Hour) will be inactivated.
