H.pylori test kits (Antigen)

$1.00
H.pylori test kits (Antigen) are Class II medical devices (FDA-cleared/CE-marked) for rapid immunochromatographic or enzyme immunoassay detection of Helicobacter pylori antigens in stool specimens, enabling non-invasive diagnosis of active infection and post-treatment eradication confirmation. Test principles use monoclonal or polyclonal antibodies specific to H. pylori antigens, producing visible results in 10-20 minutes (rapid tests) or 1-2 hours (EIA). Sensitivity 90-98%, specificity 92-99% compared to gold standard methods. Primary clinical applications include rapid diagnosis of H. pylori infection in patients with dyspepsia, initial screening in uncomplicated dyspepsia (test-and-treat strategy), confirmation of active infection before therapy, post-treatment eradication confirmation (4-6 weeks after therapy), pediatric testing (preferred non-invasive method), screening in high-risk populations (family history of gastric cancer), and monitoring in patients with peptic ulcer disease or MALT lymphoma. Critical safety precautions include mandatory washout period (4 weeks off antibiotics, 2 weeks off PPIs) to avoid false negatives, proper specimen handling (universal precautions), refrigerated storage of kits (2-30°C), quality control verification, and disposal as biohazardous waste. Essential non-invasive tool for H. pylori management in gastroenterology and primary care.

Rota virus

$1.00
Rota virus rapid tests are immunochromatographic assays (CE-marked, FDA-cleared for some brands) for qualitative detection of rotavirus group A antigens in stool specimens, providing results in 10-20 minutes. The test principle uses monoclonal or polyclonal antibodies against rotavirus antigens (typically VP6 protein) immobilized on membranes, capturing antigens that form a visible line. Sensitivity 90-98%, specificity 95-99% compared to ELISA or PCR. The kit includes individually foil-wrapped test devices, sample diluent, and collection applicators. Primary clinical applications include rapid diagnosis of acute gastroenteritis in children (rotavirus is the leading cause of severe diarrhea in under-5 children), outbreak investigation in daycare centers and schools, hospital infection control and isolation precautions, differential diagnosis of acute diarrhea (viral vs. bacterial vs. parasitic), vaccine effectiveness monitoring and surveillance, assessment of dehydration risk, and evaluation of immunocompromised patients. Critical safety precautions include proper specimen collection (clean container, avoid contamination), biological hazard precautions (all stool potentially infectious), quality control verification, and awareness that a negative test does not rule out other causes of gastroenteritis. Essential tool for pediatric gastroenteritis management, infection control, and public health surveillance.
