About Our Lactose Tolerance Test

Fasting Instructions:
Fasting is required for this lab test. You should not consume food or beverages other than water for at least 8 hours prior to visiting the lab. If you choose not to fast, it may affect your results

Our Lactose Intolerance/Tolerance lab testing is a test panel that uses a blood sample to determine if you have an intolerance to Lactose, a milk sugar. Four 1-millimeter blood samples are collected at different intervals after the individual's fasting blood sample is collected-- after which the patient takes a 50-gram dose of lactose and a blood sample is collected after 1/2-hour, 1-hour, 2-hours, and 3-hours.

Lactose allergies are also known as lactose intolerance. Lactose intolerance affects 60% of adults. In the case of a lactose allergy, the body cannot break down the lactose, a sugar found in milk and other dairy products. This can causes abdominal pain, bloating, flatulence, nausea, diarrhea and/or skin rashes.

Did you know: Lactose intolerance tends to occur overtime in adults; with occurrences more often in Native Americans and people of South America, Asian or African decent.

About Our Lactose Intolerance Test

Our Lactose Intolerance test is a much more in-depth procedure than our cow's milk allergy. This test requires that individuals fast for 8 hours prior to testing. A blood sample is drawn with the fasting blood. Then a 50g dose of lactose is administered to the patient via water solution. The lab tech will then collect subsequent blood samples from the patient at 30 minutes, 60 minutes, 90 minutes, and 120 minutes following the lactose administration.

Lactose Intolerance Vs. Dairy Intolerance Test

Our cow's milk allergy test is a regular allergy test done to discover IgE (Immunoglobulin E) antibodies. Which is basically a blood test done to determine the body’s immune response to certain allergens. Blood is drawn and using an immunoassay methodology; it’s assessed to see if certain antigens will stimulate a specific immune response by looking at the proteins produced by the immune response.

For our cow’s milk test, it shouldn’t take more than 5 - 10 minutes. Patients simply need to sign in to the lab, get their blood drawn, and they can leave. Our lactose intolerance testing is a lot more extensive, however, and patients will need to stay and get their blood drawn multiple times over the course of 2 hours.

For all of our tests, we have a 1 -3 business day turnaround. Results will be uploaded to the customer's secure account.
