A hydrogen breath test (or HBT) is used as a diagnostic tool for small intestine bacterial overgrowth and carbohydrate malabsorption, such as lactose, fructose, and sorbitol malabsorption. The test is simple, non-invasive, and is performed after a short period of fasting (typically 8–12 hours). Hydrogen breath tests are based on the fact that there is no source for hydrogen gas in humans other than bacterial metabolism of carbohydrates. Even though the test is normally known as a "hydrogen" breath test, some physicians may also test for methane in addition to hydrogen. Many studies have shown that some patients (approximately 35% or more) do not produce hydrogen but actually produce methane. Some patients produce a combination of the two gases. Other patients, who are known as "non-respond

  • اختبار التنفس الهيدروجيني هو اختبار لقياس نسبة الهيدروجين في الزفير، يتم عادة باستخدام جهاز للنفخ حيث يتم قياس الغاز وإظهار نسبته. يستخدم خصوصا لقياس متلازمة فرط النمو الجرثومي في الأمعاء الدقيقة و سوء امتضاص السكريات (اللاكتوز، الجلوكوز أو الفركتوز)، و يعتبر تدخلًا غير جراحي عملي. تختلف الاجهزة من حيث الدقة و الحجم ويقيس بعضها الميثان ايضًا. يتم الإجراء في العيادة أو المشفى وفي بعض الأماكن تتوفر أطقم خاصة لتمكين المرضى من إجراءه في المنزل.

  • A hydrogen breath test (or HBT) is used as a diagnostic tool for small intestine bacterial overgrowth and carbohydrate malabsorption, such as lactose, fructose, and sorbitol malabsorption. The test is simple, non-invasive, and is performed after a short period of fasting (typically 8–12 hours).

Even though the test is normally known as a "hydrogen" breath test, some physicians may also test for methane in addition to hydrogen. Many studies have shown that some patients (approximately 35% or more) do not produce hydrogen but actually produce methane. Some patients produce a combination of the two gases. Other patients, who are known as "non-responders", don't produce any gas; it has not yet been determined whether they may actually produce another gas. In addition to hydrogen and methane, some facilities also utilize carbon dioxide (CO2) in the patient's breath to determine if the breath samples that are being analyzed are contaminated (either with room air or bronchial dead space air). Physicians have expressed concern at the improper use and widespread overdiagnoses related to interpretation of these tests. (en)
