The Lactose Tolerance Test checks how your body handles lactose, the sugar found in milk. Some labs call it a lactose tolerance blood test, a lactose tolerance glucose test, or a lactose malabsorption test. You can book this test at participating labs through LabFinder and pick a time that fits your schedule.
A lactose tolerance blood test or lactose tolerance glucose test measures your blood sugar after you drink a set amount of lactose. If your blood sugar does not rise as expected, it suggests your body is not breaking down lactose well. In simple words, it helps check for lactose intolerance.
Common reasons: frequent gas, bloating, or diarrhea after dairy, tummy cramps that follow milk or ice cream, checking possible lactose intolerance when symptoms are unclear, or confirming results when a doctor needs a blood based test instead of a breath test.
Plan about 120 to 180 minutes at the lab. You will check in and have a first small blood draw. You will drink a sweet lactose drink. The team will draw more small blood samples at set times over the next two to three hours. You can sit, read, or use your phone between draws. A bandage is placed after each draw.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. Drinking the lactose solution can cause short term gas, cramps, or loose stools if you are lactose intolerant.
Fasting: Do not eat or drink anything but water for 8 to 12 hours unless your doctor says otherwise. Medicines: Ask your doctor about antibiotics, acid reducers, or diarrhea medicines that could affect testing plans. No smoking or hard workouts: Avoid these the morning of your test. Tell the team if you have diabetes: Your doctor may adjust the plan. Bring prior results: Any past breath tests or lab work helps with comparison.
Lactose intolerance, long lasting bloating and gas after dairy, belly cramps linked to milk, diarrhea related to dairy, nutrition concerns from avoiding dairy, and mixed bowel symptoms that your doctor is trying to sort out.
