Dr. Narendra Saini, MBBS, MD, Internal/General Medicine, will discuss about blood culture in this video. He says that when there is a suspicion of microorganisms or septicaemia in the blood, then blood culture is done. Before taking a blood culture, a bottle, a syringe, an alcohol swab, chlorhexidine or iodine swab and a tourniquet is needed. Also, he mentioned that the organisms needed to be collected should be from the blood only not from the skin flora. Skin should be sterilized by antiseptic chlorhexidine or iodine swab. The blood collection is generally from the elbow area. While collecting the blood, the bottle of the blood culture mentions how much blood needs to be drawn.
