13c urea breath rapid reagent 75mg
There are many methods for HP diagnosis. The only detection method with the highest sensitivity and specificity (close to 100%) is the urea breath test, which is the "gold standard" for the evaluation of the efficacy of Hp infection and reflects the Hp infection in the stomach. 13c ubt rapid reagent is the best method for detecting Hp infection in the stomach. It is widely used in children and pregnant women, as well as the diagnosis of Hp and the review and monitoring of the effect of Hp treatment.
Carbon 13-urea breath test inspection range:
Newly diagnosed patients with dyspepsia; patients who are unwilling to have gastroscopy; gastroscopy with negative urease but suspected of Hp infection; follow-up of the effect of Hp eradication treatment; carbon 13 breath testing can be done in routine physical examinations.
Reagents for carbon 13-urea breath test
The product is white particles, accompanied by orange and sour taste, some people feel it is sweet and salty, and the taste is different. Easily soluble in water. Each 5g bottle contains 75mg of urea [13C], molecular formula of urea [13C]: 13CO(NH2)2, molecular weight: 61.06, and its chemical name is carbamide. Oral urea [13C] is absorbed rapidly, reaching a peak within 0.11 hours, and clearing quickly, with a renal clearance rate of 0.617L.Kg-1.H-1. The excretion is mainly urine, and the excretion of feces and urine within 24 hours reaches 65%. The carbon isotopes are 12, 13, and 14, of which 12 and 13 are nuclear stability elements, which are not radioactive, and the reagent does not have any side effects.

The relationship between the DOB value of carbon 13-urea breath test and the amount of Hp
Different Hp strains have different ability to express urease. Therefore, the DOB value of carbon-13-urea breath test may also be different, but most of the DOB value is related to the Hp density, the severity of gastritis and the activity of gastritis.
