Carbapenemase Detection by Rapid Immunochromatographic Assay (Qualitative)
This test checks for the presence of carbapenemase enzymes in a bacterial sample, which can make certain antibiotics ineffective. It helps healthcare providers identify bacteria resistant to powerful antibiotics like carbapenems.

Why This Test Is Done
Your doctor may order this test if you have symptoms of an infection—such as fever, chills, or persistent cough—and are being treated with carbapenem antibiotics. It’s also used in hospital settings to quickly identify resistant bacteria in patients with suspected infections.
How the Test Works
The test uses a rapid immunoassay (a strip-based method) to detect carbapenemase enzymes in a bacterial sample. A small amount of your bodily fluid (often urine, blood, or other clinical specimens) is tested for these enzymes, which break down carbapenem antibiotics.
Sample Collection and Processing
The test typically involves collecting a clinical specimen (e.g., urine, blood, or sputum) that may contain bacteria. The sample is processed quickly to detect carbapenemase enzymes within minutes, allowing for faster treatment decisions.
What to Expect After the Test
You may receive results immediately or within a few hours, depending on the lab’s workflow. If the test is positive, your doctor will adjust your treatment plan to use alternative antibiotics that are effective against carbapenemase-producing bacteria.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Carbapenemase-producing bacteria are a growing concern because they resist multiple antibiotics, including carbapenems—the last line of defense against many serious infections. Detecting these enzymes early helps prevent antibiotic resistance in hospitals and communities, ensuring better treatment options for patients.
