Below are examples of notes za wizara of HISTORICAL AND CYTOLOGICAL TECHNIQUE

       Specimen for cytological investigations can be obtained from different sources including body cavity fluids, aspirates, tissue touch/impression, urine, sputum and nipple discharge.

       From these entire specimens the aim is to harvest enough cellular materials that can be processed for microscopic examination. Universal precautions should be followed when handing tissue specimens including the use of PPE.

       As soon as cells are spread on a microscope glass slide to make a smear, should immediately be fixed. If received fluid specimen, it has to be centrifuged or cytospinned. From the centrifuged, deposits are used be centrifuged which will immediately be fixed.

       Fixed smears are then stained using stain of choice followed by mounting.

       Routinely used cytological stain is Papanicolaou’s Stain.

       Cytological smear is not allowed to dry until being mounted. However, if micro-organism are thought to be demonstrated cytological smear has to be air-dried followed by staining. Stained mounted smear, can be examined under microscope, transported or archived.
