test
A blood culture test is a routine test that can be used to check for the 
presence of bacteria, yeast, or other microorganisms in the blood that can 
cause significant damage to the immune system and internal organs of 
the body. Bacteremia also called bacterial infection in the blood can be 
serious because the blood can spread the bacteria to any part of the body. 
Other serious infections will occur due to blood infections. That will affect 
the lungs, kidneys, bowel, gallbladder, or heart valves. This blood culture 
test is done by a Microbiologist. If you are searching for

Some blood culture test that is used to diagnose 
the infections are as follows:
• Endocarditis – a serious and life-threatening problem that occurs when 
bacteria in the bloodstream attach themselves to the valves of the 
heart.
• Osteomyelitis – Staphylococcus also called a bone infection that is 
caused by a bacteria 
• Cellulitis – skin diseases that involve the subcutaneous tissue.
Symptoms are as follows:
•  Colds,
•  Disorder in lifelike confusions
•  Decrease urine or less repeated urination,
•  High-temperature fever.
Tends to more development of more severe 
symptoms because of the high level of infection, 
such as:
•  Body pain and tiredness throughout the body.
•  The smallest blood vessels make the formation of several tiny blood clots.
•  Decreasing blood pressure.
•  Very chance to get a failure of one or more organs of the body.
Know how the blood culture test done
Using a sterilized syringe a small amount of blood is drawn from one of 
the veins for a blood culture test. The area is cleaned with an alcohol swab 
to make the area bacteria-free before pricking the skin. A particular 
quantity of blood is drawn in a specific sample test tube, once the needle 
is inserted in one of the veins. To performing a blood culture and examine 
the presence of infection in the body, this sample is then sent to the lab.
Risk factors in blood culture test:
In some cases, there is a little chance to get problems at the time of the 
blood sample collection:
•  excessive bleeding from the site
•  infection occurs
•  chance of fainting
•  vein inflammation
•  hematoma, or bruising
What’s the test result mean:
To find an infection in the blood is called blood culture. In culture, most of 
the bacteria can be seen in 2 to 3 days, but some types can take 10 days 
or more to appear. To appear fungi culture it will take 30 days. 
 
•  In normal blood culture, no bacteria or fungi were found then the
        test result will be negative. 
•  In abnormal blood culture, bacteria and fungus will grow then the
        result is positive.
Another test will be done to find the best antibiotic if bacteria are found in 
the culture. That will kill the bacteria. This process is called sensitivity or 
susceptibility testing. To treat blood infections correctly, sensitivity testing 
is important. Some microorganisms are there which cannot grow or find it 
difficult to grow in culture. Therefore, extra blood culture may be needed. 
Sometimes using blood culture test virus cannot be detected, In that case, 
depends upon the person's clinical symptoms and signs of the type of 
virus suspected by the doctor give some general prescription. Search the
