What is this test?

This test looks for DNA from Enterobacter bacteria in a whole-blood sample. It uses nucleic acid amplification to make any bacterial genetic material present easier to detect and reports a qualitative result.

Why might I need this test?

Your clinician may order this test when you have signs of a bloodstream infection, such as fever, chills, weakness, confusion, or low blood pressure. It may be considered when Enterobacter infection is suspected, particularly in people with weakened immune systems.

How is the test performed?

A blood sample is collected and processed in the laboratory. The test targets specific Enterobacter DNA sequences and reports whether target DNA was detected; it does not measure the amount of bacteria in the blood.

How do I prepare for the test?

No fasting or special preparation is usually required. Follow your clinician's instructions, especially if the test is being done urgently because of possible sepsis, and do not delay necessary care to prepare.

Frequently asked questions

What does a positive result mean?
A positive result means Enterobacter DNA was detected in the blood. In the right clinical setting, this may indicate bloodstream infection, but the result should be reviewed with your symptoms, examination, and other tests.
Does a negative result rule out a bloodstream infection?
No. A negative result lowers the likelihood of Enterobacter being detected but cannot rule out all infections or every case of sepsis. Your clinician will interpret it along with your overall condition.
Does this test determine which antibiotics will work?
Not by itself. Antibiotic susceptibility testing generally requires growing the organism from a blood culture or another infected-site specimen.
