Blood Culture (bacterial, fungal, and/or AFB)
- Gram stain – which is used to detect and identify the type of bacteria present in other body sites like urine or sputum
- Susceptibility tests determine which drug will be ideal for treating the infection
- Chills, fever
- Rapid breathing, rapid heartbeat
- Less frequent urination
- Inflammation throughout the body
- The formation of many tiny blood clots in the smallest blood vessels
- A dangerous drop in blood pressure
- The failure of one or more organs
- Some types of microbes tend to be challenging to grow in culture. In this case, the laboratorian adds blood cultures in order to try to grow and identify the pathogen.
- Some viruses cannot be detected using blood culture bottles designed to grow bacteria. However, if the doctor suspects that a viral infection is causing the patient's symptoms, then he or she may order other laboratory tests to be performed. The tests that they order are contingent on the patient's clinical signs and the type of virus the doctor suspects is causing the infection.
- Complete blood count (CBC). An increased white blood cell (WBC) count (or in some cases a decreased WBC count) may indicate infection.
- Complement Levels of C3 may be increased.
- A urine or sputum culture may be positive, suggesting that a possible source of infection may have spread to the blood.
- CSF analysis may identify a possible source of infection.
