Almost 65% of people worldwide are lactose intolerant to some degree — this simple, painless cheek swab test helps you find out if your digestive symptoms may have a genetic cause. Results are delivered privately and confidentially online.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1443\/4772\/products\/lactose_front.jpg?v=1776384745\" alt=\"DNA Lactose Intolerance Test kit front panel showing MCM6 gene variant analysis and at-home cheek swab collection\" style=\"max-width:100%;height:auto;\"\u003e\n\n\u003ch2\u003eDNA Lactose Intolerance Test, Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAnalyzes five common genetic variants in the MCM6 gene linked to lactose intolerance\u003c\/li\u003e\n\u003cli\u003eDifferentiates between lactose intolerance and lactase persistence\u003c\/li\u003e\n\u003cli\u003ePainless buccal (cheek) swab sample collection, no needles or clinic visit required\u003c\/li\u003e\n\u003cli\u003e100% private and confidential online results\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLactose Intolerance vs Lactase Persistence\u003c\/h2\u003e\n\u003cp\u003ePeople who are lactose intolerant cannot digest and absorb the milk sugar lactose, because they produce only low levels of the lactase enzyme. This causes digestive symptoms such as gas, bloating, and diarrhea when dairy products are consumed. Lactase persistence is the opposite — people who are lactase persistent produce the lactase enzyme throughout their lives and can continue consuming dairy into adulthood without symptoms.\u003c\/p\u003e\n\n\u003ch2\u003eThe Genetics Behind Lactose Intolerance\u003c\/h2\u003e\n\u003cp\u003eGenetic variation is the strongest predictor of lactose intolerance and lactase persistence. The MCM6 gene encodes a protein that controls the production of other proteins, including lactase encoded by the nearby LCT gene. People with at least one of the five tested MCM6 variants are unlikely to suffer from lactose intolerance. Those who do not carry any of these variants have an increased risk of lactose intolerance.\u003c\/p\u003e\n\u003cp\u003eThe likelihood of lactose intolerance varies significantly by ethnicity. Lactose intolerance affects approximately 90% of Asian Americans, 70% of African Americans, 95 to 100% of Native Americans, and 50% of Mexican Americans. In contrast, fewer than 25% of Caucasians and only about 5% of people of Northern European ancestry are lactose intolerant, reflecting a long history of dairy as a dietary staple.\u003c\/p\u003e\n\n\u003ch2\u003eSymptoms of Lactose Intolerance\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBloating and abdominal distension\u003c\/li\u003e\n\u003cli\u003eFlatulence and gurgling sounds from the abdomen\u003c\/li\u003e\n\u003cli\u003eDiarrhea\u003c\/li\u003e\n\u003cli\u003eNausea or vomiting\u003c\/li\u003e\n\u003cli\u003eAbdominal pain or cramps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow It Works\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003eOrder your DNA Lactose Intolerance Test kit online and receive it at home\u003c\/li\u003e\n\u003cli\u003eRegister and activate your kit, then collect your DNA sample using the painless cheek swab provided\u003c\/li\u003e\n\u003cli\u003eMail your sample to the lab in the prepaid return envelope\u003c\/li\u003e\n\u003cli\u003eReceive your results securely online\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does it mean if I test positive for lactose intolerance risk?\u003c\/strong\u003e\u003cbr\u003eA result indicating increased lactose intolerance risk means you do not carry the MCM6 gene variants associated with lactase persistence. This suggests your body may produce lower levels of the lactase enzyme, making it harder to digest dairy. Discuss your results with a healthcare provider or registered dietitian for personalized dietary guidance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I still eat dairy if I have a high-risk result?\u003c\/strong\u003e\u003cbr\u003eMany people with lactose intolerance can tolerate small amounts of dairy or choose lactase enzyme supplements to aid digestion.
