Lactose Tolerance
This test will collect multiple blood samples. An initial “baseline” draw will be collected.
Then, you will be given lactose (dissolved in water), and a new blood sample will be drawn every 30 minutes for the next 2 hours. You will be allowed to drink water during the test, but cannot chew gum or smoke.
The test assesses your samples for glucose because lactose is converted to glucose by the liver. An increase in glucose is expected after taking lactose. A glucose level that is very low might indicate lactose intolerance.
Test results may take 1-2 business days.
