Culture Aerobic Blood (Automated)
What is Culture Aerobic Blood (Automated)?
The Culture Aerobic Blood test is done to check for the presence of systemic infection. It is also done to detect and identify the presence of bacteria or yeast in blood.
Why is Culture Aerobic Blood (Automated) done?
The Culture Aerobic Blood test is done:
In case of signs or symptoms of infection or sepsis-like fever, rapid heart rate, nausea, confusion, and reduced frequency of urination
In case of recent infection, surgical procedure, valve replacement or when there is a high risk of systemic infections
What does Culture Aerobic Blood (Automated) Measure?
The culture aerobic blood test is done to detect an infection in the blood and to identify its cause. Bloodstream infections are most commonly caused by bacteria, yeasts, fungi, or virus.
The blood infection usually originates from a specific site within the body. It then further spread when a person gets affected by a severe infection such as in the case of urinary tract infection. The infection may spread from the bladder and/or kidneys into the blood and can be further spread throughout the body infecting other organs and causing life-threatening systemic infection.
Those who have a weakened immune system due to diseases such as leukemia or HIV/AIDS or due to chemotherapy are at higher risk for blood infections. This is due to their weak immune system which is not efficient enough to kill microbes entering the blood.
The bacterial and yeast infection can be introduced directly into the bloodstream through intravenous drug use or through surgical drains or intravenous catheters.
For culture aerobic blood test, multiple blood samples are collected for testing. Samples for the blood test are taken from different veins to increase the chances of detecting the bacteria or fungi. The blood cultures are incubated for a few days before reporting a negative result as some bacteria and fungi take time to grow and may take longer to detect.
In some laboratories, the process of culture aerobic blood test is automated with instruments which continuously monitor the bacteria or fungi growth. The advantage of this method is the timely reporting of results which helps in providing proper treatment against the detected microbes present in the blood.
Interpreting Culture Aerobic Blood (Automated) results
Two or more blood cultures that are positive for the same bacteria or fungi means that the person tested likely has a blood infection with that organism. The results typically identify the specific bacteria or fungi causing the infection.
If one blood culture set is positive and one set is negative, it may mean that an infection or skin contaminant is present. Additional tests are done in such cases.
If blood culture sets are negative after several days (no growth), then the probability that the person has a blood infection caused by bacteria or fungi is low.
