Why This Test Might Be Ordered
Your healthcare provider may order this test if you have symptoms like fever, chills, or signs of infection (such as redness, swelling, or pain) and have been prescribed tigecycline. It can also be used to confirm if bacteria are present in your blood when other tests are inconclusive.
What to Expect Before the Test
No special preparation is needed. You may have a small bruise or slight discomfort at the needle insertion site, but this usually goes away quickly. If you are on blood thinners, inform your provider before the test.
During the Test
A healthcare professional will insert a needle into a vein in your arm or hand to draw a small amount of blood. The blood sample will be sent to a lab where it is examined under a microscope to look for bacteria.
After the Test
You can return to your normal activities immediately. Apply gentle pressure to the injection site to stop any bleeding. If you experience excessive bruising, swelling, or pain, contact your healthcare provider.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result means that bacteria are visible under the microscope in your blood sample. This finding can indicate an infection that may require additional testing, such as cultures for antibiotic sensitivity, or further medical intervention. Tigecycline is used to treat serious infections caused by certain bacteria, so a positive result may guide treatment decisions.
