BLOOD SAMPLING : In blood sampling, the skin is deliberately punctured in order to take a blood sample for analysis. If this is done carelessly, it is easy for microorganisms either to enter the blood stream of the donor from the lancet used, or from the donor's blood to enter the environment and contaminate it. The most common serious diseases transmitted are viral hepatitis and AIDS. Both of these diseases can be transmitted through small cuts. Therefore, you should always use fresh and sterilized needle to prick the finger tip for the blood sample.
Disposal of the needle should be done in the same way as for the sharps. Rubber gloves should be used while taking and handling the blood samples.
