The process is not only pricking the patient and collecting the blood, it involves a thorough preparation including mental make as well. Since childhood everyone is skeptical about a needle prick. Nobody likes to be get pricked. Many of the patients are apprehensive about the pain associated with needle prick. In fact some sensitive patient does not allow pricking in one request. You need to make a good conversation and make the patient feel assured that the needle prick is not very painful procedure. This is particularly applicable for the persons getting needle prick for the first time. You should also be ready to face such situations. Apart from the technical aspects about blood collection, this part should also be taken care of with due precautions. Particularly children are a difficult group to handle. They tend to resist needle prick. You really need to be very calm and composed in such situations. Even if you are working in a busy laboratory; you need to be courageous to clear the apprehensions of the children. If the children are small and cannot be counseled, you need to take help of parents of these children. Make a good conversation with the parents of the child.
