Bulk Point Of Care Testing Working聽Principle聽And聽Intended聽Use The聽portable glycosylated hemoglobin analyzer聽uses聽boric聽acid聽affinity聽chromatography聽and聽optical聽principles to聽determine聽the聽percentage聽of聽glycosylated聽hemoglobin聽in聽total hemoglobin. Using聽the聽principle聽of聽the聽reversible聽combination聽of聽glucose聽cis-diitol聽and the聽boronic聽acid聽group, the聽boronic聽acid聽group聽is聽firmly聽bound聽to聽the solid phase聽carrier聽through聽a聽covalent聽bond聽to聽prepare聽an聽affinity adsorption聽system聽. In聽stage聽A, hemoglobin-including聽glycated聽and聽non-glycated聽parts-flows with聽buffer聽A聽and聽is聽fixed聽on聽the聽carrier. At聽this聽time, the聽light聽intensity聽of聽total hemoglobin聽is聽measured聽by聽the聽detection聽light聽emitted聽from聽the聽inside聽of聽the analyzer. In聽stage聽B, after聽adding聽buffer聽B, glycosylated聽hemoglobin聽binds聽specifically to聽the聽boronic聽acid聽group聽on聽the聽carrier聽stationary聽phase, while聽other non-glycated聽hemoglobin聽is聽eluted聽by聽buffer聽B. At聽this聽time, measure聽the light聽intensity聽of聽glycosylated聽hemoglobin聽through聽the聽detection聽light emitted聽from聽the聽analyzer. Finally,聽the聽portable glycosylated hemoglobin analyzer聽calculates聽the聽percentage聽of聽glycosylated聽hemoglobin to聽the聽total聽hemoglobin聽based聽on聽the聽results聽of聽the聽light聽intensity聽measured in聽the聽A聽and聽B聽stages, thereby聽quantitatively聽detecting聽glycosylated聽 hemoglobin.

The analyzer can also be connected to a USB power adapter or a mobile power supply (power bank) that meets the specified specifications. Generally, in order to avoid unnecessary聽 power聽 consumption聽 of聽 alkaline聽 batteries,聽 we聽 suggest聽 that computers, USB power adapters or mobile power sources (power banks) should聽 be聽 preferred聽 to聽 be聽 used聽 for聽 power聽 supply,聽 so聽 as聽 to聽 extend聽 the service life of alkaline batteries and reduce frequent battery replacement . Product features 1)Accuracy:聽Use the reference material as a sample for testing, and the relative deviation of the analyzer's measurement results should be within the interval of +8%. 聽 2)聽Repeatability:聽For samples with a sample concentration of 4.0%~ 6.5%(20.2mmol/mol-47.5mmol/mol), the coefficient of variation CV of the repeated measurement results of the analyzer should not be greater than 3%. 聽 3)Linearity: Within the analyzer delecto testi/revallot40% to 14.0%, the linear tYrelation coeficient."7" of the test resulls should not be less than 0.99. Installation and maintenance of top panel and test strip presser Before testing, please make sure the top panel and test strip presser are inserted properly into the portable glycosylated hemoglobin analyzer . The optical area must be clean and free of residue. Residual water stains,聽 cotton threads and foreign particles may affect the accuracy of detection. In order to get accurate test results, the analyzer needs to be cleaned after daily use.聽 Sample聽test聽operation聽process StepOperationIllustration 聽聽 1Test聽strip聽insert Open聽the聽package, take聽out聽the聽test聽strip,聽confirm聽the聽correct聽direction聽of聽the聽test strip,聽insert聽the聽test聽strip聽into聽the聽analyzer,聽until聽the聽location聽marking聽line聽on聽the聽test 聽strip聽coincides聽with聽the聽edge聽of聽top聽panel.聽聽聽聽聽 2Check聽card聽No. Check聽whether聽the聽test聽strip聽No. displayed聽by聽the聽analyzer聽is聽consistent 聽聽with聽the聽code聽on聽the聽test聽strip聽packaging box/bag.

Or according to actual condition to clean and disinfect the聽 portable glycosylated hemoglobin analyzer. 2)聽 聽 After daily use, clean the surface of top panel, test strip presser and聽 optical area according. Before cleaning, slide the top panel out of the analyzer and lift up the test strip presser. Use 75% medical alcohol to clean and disinfect all outer surfaces. The optical area must be clean and free of residue. Residual water stains, cotton threads and foreign particles may affect the accuracy of detection. 3)聽 聽 After cleaning, after the surface is completely dry, install the top panel and test strip presser back on the analyzer. Maintenance 1)聽 聽 Pay attention to the use of the battery of analyzer during normal use. If the battery is found to be low, should be replaced in time. 2)聽 聽 Regularly open the battery cover to check the batteries, so as to avoid that the battery is unused for a long time or is seriously damaged,聽 聽 聽 聽which may cause battery leakage and damage the analyzer.
