Revolving stool for the lab technicianAdequate facilities for laboratory record, chemicals, cleaning of slides, staining, etc.Condition of MicroscopeOil-immersion lens and eye-piece free from dust, dirt or opacityCoarse and fine adjustments in good working conditionMechanical stage moving without jerks / zigzag movementCare of the microscope Always keep the microscope covered with a clean plastic or cloth cover when it is not in use toprotect it from dust, especially in hot dry climates Protect microscope from fungus growth in warm humid climate by either:o Storing it in a continuously air-conditioned or de-humidified room oro Fixing a 15- watt bulb, which is left constantly lit, in the microscope box oro Connecting a number of 15- or 25-watt bulbs, left constantly lit, inside a cupboard withtightly fitting doors Clean the immersion oil from the immersion objective every dayCleaning and storing microscope slides New slides should be soaked in water with detergent for 30-60 minutes and then rinsed severaltimes under running tap water. Dry each slide using a clean, lint-free cloth. Previously used slides must be soaked for at least 1 hour in hypochlorite solution before beingwashed and dried. Slides for preparation of blood films must be scrupulously clean and free from moisture, grease andscratches.Checking random samples of blood smearsRandom samples of blood smears to be picked up from slides stained over the preceding week. At least20-25 slides to be checked for the following:Presence of both thick and thin smearsSerial number of the slide: clearly legible on thin smearThe quality of smear and staining to be judged visuallyThick smear to have adequate blood about 1 cm in diameter and have light blue stain colour withviolet iridescenceThin smear to be single layered and tongue shapedGlass slides to be free from dust, dirt, greasy spots and scratchesStaining and artifacts to be checked from slides of each subcentreRandom confirmation of positives for species and stagesRe-examination of all blood smears of severe and complicated P. falciparum infection for species,stages and density of parasites.25
Examination of blood films for malaria parasites (various blood stages of P. falciparum andP.vivax are shown in Plates 1 and 2 respectively)Examination of thick filmsExamine 100 fields, following the pattern of movement shown. To assist in examination, use a handtally counter to count fields. Record findings on the appropriate record form. A parasite count may beincluded. Examine the blood film following the pattern of movement shown.Examination of thin filmsIt is usually in the distal third of the blood film that cells are: Most evenly distributed In a single layer and Have minimum distortionExamine the blood film following the pattern of movement shown. Examination of thin films may benecessary for confirmation of species identification or when thick films have been poorly prepared.Methods of counting malaria parasites in thick blood filmsIt is often necessary to determine the density of malaria parasites in thick blood films so that thephysician is aware of the severity of the infection and the parasites are responding to treatment. Twomethods are employed to count the parasites in thick blood films: Determination of parasites /l of blood Plus systemDetermination of parasites / ml of blood(a) If, after counting 200 leukocytes, 10 or more parasites are found, record the results in terms ofnumber of parasites / 200 leukocytes. Using a formula, multiplying the number of parasites by 800026
