Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like fever, chills, or signs of infection such as redness, swelling, or pain at an injection site. It can also be used to monitor people with known infections or those at higher risk, such as those with weakened immune systems.
How the Test Works
A small amount of blood is drawn and placed in a special container. Microscopic examination looks for bacteria that may have grown or are present in the bloodstream. This is often done quickly, sometimes within hours, to provide early results.
What to Expect Before the Test
You may experience mild discomfort or bruising at the needle insertion site. Avoid eating or drinking for a short time before the blood draw if instructed. Bring any medications or supplements you take to discuss with your provider.
What to Expect During the Test
The blood draw typically takes a few minutes. You may feel lightheaded or dizzy for a moment, but this usually passes quickly. Rest and stay hydrated afterward.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results suggest the presence of bacteria in your blood, which can indicate serious infections such as sepsis. Early detection is critical to prevent complications and guide appropriate antibiotic treatment. Negative results mean no bacteria were found in this sample, but further testing may still be needed if symptoms persist.
