Internal Quality Control<\/span> <\/strong>is a process of effective and systematic internal monitoring of the working practices. It includes technical procedures, checking instruments, quality of new batches of staining solution, smear preparation, grading, equipment infection control measures, waste management, etc.<\/p>\n\n

\n\t
For the purpose of IQC, it should be ensured that all staining reagents\u2019 dye content is mentioned on the bottle, concentrated acids are stored carefully in separate containers and stains are filtered before use.<\/li>\n\t
Further, after each new batch of reagents is made, Quality Control Positive (QCP) and Quality Control Negative (QCN) slides should be prepared by the Senior TB Lab Supervisor (STLS) for quality control.\n\t
\n\t\t
QCP slides should be prepared by pooling 3+ grade sputum samples,<\/li>\n\t\t
QCN slides are to be prepared by pooling negative sputum samples with an adequate number of pus cells (\u226510 pus cells\/ field).<\/li>\n\t<\/ul>\n\t<\/li>\n\t
One set of QCP-QCN slides should be stained by STLS and another set should be given to the Designated Microscopic Centre (DMC) Lab Technician (LT) along with the reagent, and the results of both should be entered in the batch register\/ IQC document.<\/li>\n\t
All quality control slides should be stored for a minimum period of four months.<\/li>\n<\/ul>\n"},"metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"d235478c-8016-4721-9193-4674cf52ccd7"},"alwaysDisplayComments":false,"backgroundOpacity":0,"displayAsButton":false,"buttonSize":"big","goToSlideType":"specified","invisible":false,"solution":""}],"slideBackgroundSelector":{}},{"elements":[{"x":7.625272331154684,"y":12.903225806451612,"width":82.78867102396515,"height":64.73118279569891,"action":{"library":"H5P.AdvancedText 1.1","params":{"text":"

For the microscope, the lens should be cleaned with tissue paper after examining each slide and stored inside a microscope box at the end of the day.<\/li>\n\t
The microscope box should contain silica gel and an electric bulb of 10-15 watts for desiccation to prevent fungal growth on the lens. The silica gel should be dehydrated periodically under direct sunlight.<\/li>\n\t
All microscopes should be covered under the Annual Maintenance Contract (AMC) with routine preventive maintenance.<\/li>\n<\/ul>\n"},"metadata":{"contentType":"Text","license":"U","title":"Untitled Text"},"subContentId":"e86e510f-0dc5-43ca-b028-ba3723d70580"},"alwaysDisplayComments":false,"backgroundOpacity":0,"displayAsButton":false,"buttonSize":"big","goToSlideType":"specified","invisible":false,"solution":""}],"slideBackgroundSelector":{}}],"keywordListEnabled":true,"globalBackgroundSelector":{},"keywordListAlwaysShow":false,"keywordListAutoHide":false,"keywordListOpacity":90},"override":{"activeSurface":false,"hideSummarySlide":false,"summarySlideSolutionButton":true,"summarySlideRetryButton":true,"enablePrintButton":true,"social":{"showFacebookShare":false,"facebookShare":{"url":"@currentpageurl","quote":"I scored @score out of @maxScore on a task at @currentpageurl."},"showTwitterShare":false,"twitterShare":{"statement":"I scored @score out of @maxScore on a task at @currentpageurl.","url":"@currentpageurl","hashtags":"h5p, course"},"showGoogleShare":false,"googleShareUrl":"@currentpageurl"}},"l10n":{"slide":"Slide","score":"Score","yourScore":"Your Score","maxScore":"Max Score","total":"Total","totalScore":"Total Score","showSolutions":"Show solutions","retry":"Retry","exportAnswers":"Export text","hideKeywords":"Hide sidebar navigation menu","showKeywords":"Show sidebar navigation menu","fullscreen":"Fullscreen","exitFullscreen":"Exit fullscreen","prevSlide":"Previous slide","nextSlide":"Next slide","currentSlide":"Current slide","lastSlide":"Last slide","solutionModeTitle":"Exit solution mode","solutionModeText":"Solution Mode","summaryMultipleTaskText":"Multiple tasks","scoreMessage":"You achieved:","shareFacebook":"Share on Facebook","shareTwitter":"Share on Twitter","shareGoogle":"Share on Google+","summary":"Summary","solutionsButtonTitle":"Show comments","printTitle":"Print","printIngress":"How would you like to print this presentation?","printAllSlides":"Print all slides","printCurrentSlide":"Print current slide","noTitle":"No title","accessibilitySlideNavigationExplanation":"Use left and right arrow to change slide in that direction whenever canvas is selected.","accessibilityCanvasLabel":"Presentation canvas.
