(taken as standard number of leukocytes /l of blood) and then dividing this figure by the number ofleukocytes counted, the parasites /l of blood is determined, <strong>for</strong> example,If 200 leukocytes are counted and 25 parasites are counted,(25 parasites x 8000/200 leukocytes) = 1000 parasites /l of blood(b) If after counting 200 leukocytes, the number of parasites is 9 or fewer, continue counting untilyou reach 500 leukocytes and then record the number of parasites/500 leukocytes.If 500 leukocytes are counted and 5 parasites are counted,(5 parasites x 8000/500 leukocytes) = 80 parasites /l of bloodPlus systemA simpler method, albeit less satisfactory, entails using a code of between one and four plus signs, asfollows:+ = 1 - 10 parasites per 100 thick film fields++ = 11 - 100 parasites per 100 thick film fields+++ = 1 - 10 parasites per single thick film field++++ = More than 10 parasites per single thick film fieldInspection of records <strong>for</strong> time lagA sample of M - 4 <strong>for</strong>ms should also be seen especially to note the time taken between: Making of slides at periphery to receipt at the laboratory Period between receipt in laboratory and staining Period between staining and examination of slides Period between examination of slides and dispatch of results to the periphery <strong>for</strong> effective treatmentNecessary supervision must be exercised by MO-PHC over the lab technician and corrective actiontaken <strong>for</strong> minimizing time lag between slide making and receipt of report by <strong>health</strong> provider.Cross checking of activities from recordsStatus of active case detection and population coverage.Whether MPWs are visiting all villages at <strong>for</strong>tnightly interval round the year and if not, the reasons<strong>for</strong> such defaultWhether MPWs are collecting adequate number of blood smears from all the villages during theirdomiciliary visitsAny fungal growth in stains and buffer water, proof of daily filtering of stains, stock register,verification of drugs and chemicals, reagents of analytical grade, distribution of drugs andmicroscopy slides to DDC, FTD, etc.Daily work load of technicians as per norms vis-à-vis backlog of blood smears.27
