Blood Culture Test in Bangalore
Blood culture is a laboratory test in which we take a venous sample of blood from the arm is taken. The sample collection may be repeated another 2-4 times to make the results more accurate. The blood samples are taken and mixed with an appropriate growth media to culture the organisms, in simple words to allow them to multiply. The culture media has the right nutrients that encourage the growth of bacteria that may be invading the blood and causing illnesses like lung infection, kidney infection, heart infection, or a generalized infection of the bloodstream called sepsis which is serious. This test helps to select the right set of antibiotics to control the infection thus preventing unnecessary or excess antibiotics.
The results from the blood culture along with the identification of the organism causing illness are available in 3-4 days as that is the time required for the bacteria to appear in detectable numbers. Some bacteria may take longer up to 6-7 days to multiply as they multiply slowly like T.B bacteria.

FAQs
What Is a Blood Culture?
A blood culture is a test that looks for microorganisms in the blood (such as bacteria or fungi). If germs are discovered, the test can also help doctors determine which medications will be most effective in treating the infection.
What is the test procedure for a Blood Culture test?
The majority of blood tests draw a little amount of blood from a vein. A health professional will perform the following to do this:
- clean the skin
- put an elastic band (tourniquet) above the area to get the veins to swell with blood
- insert a needle into a vein (usually in the arm inside of the elbow or on the back of the hand)
- pull the blood sample into a vial or syringe
- take off the elastic band and remove the needle from the vein
- Collecting a sample of blood is only temporarily uncomfortable and can feel like a quick pinprick.
What do the results of blood culture mean?
A positive culture means that a particular bacteria or yeast-like fungi are present in your blood. Repeating positive cultures of a particular organism implies that that particular organism is behind the blood infection causing illness. A negative result implies that blood is clear of any bloodstream infection and we need to look for other causes of the illness.
How do you know that a blood culture is positive for a certain organism?
Blood culture positive for an organism will show up as a growth on the culture Petri dish. Based on what the organism is, there will be a variation in the growths called colonies. These variations could be in the color, size, shape, luster, number, etc. which are specific to a particular organism.
