Fluoroquinolone Antibiotic Resistance Probe (Serum/Plasma)
This test detects the presence of genetic markers linked to antibiotic resistance in fluoroquinolone drugs, which are commonly used to treat bacterial infections.
["Helps determine if bacteria may be resistant to fluoroquinolone antibiotics before treatment begins."]

What This Test Measures
This test analyzes genetic material (DNA) from bacteria in your serum or plasma to check for specific mutations. These mutations can make bacteria resistant to fluoroquinolone antibiotics, which are used to treat infections like urinary tract infections, pneumonia, and certain types of skin infections. The probe detects these genetic changes to help guide treatment decisions.
Why It Might Be Ordered
Your healthcare provider may order this test if you have a bacterial infection that doesn’t respond well to fluoroquinolone antibiotics, or if you’re considering this type of treatment. It’s also used in research or clinical settings to monitor antibiotic resistance trends in bacteria.
How the Test Works
The test uses a molecular probe to identify genetic sequences associated with fluoroquinolone resistance. A small sample of your blood (serum or plasma) is collected and analyzed in a laboratory. The probe binds to specific DNA sequences if they’re present, indicating potential resistance.
Preparation for the Test
No special preparation is needed for this test. You may have a simple blood draw, similar to other routine blood tests. If you’re taking antibiotics, let your healthcare provider know before the test, as it may affect results.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Short name
Fluoroquinolone Resistance Test
Frequently asked questions
This test helps healthcare providers determine if bacteria causing your infection are resistant to fluoroquinolones. Early identification of resistance can lead to more effective treatment choices, reducing the risk of ineffective therapy or antibiotic resistance in the community.
