Carbapenemase Detection by Rapid Immunochromatographic Test (Serum/Plasma)
This test checks for the presence of carbapenemase enzymes, which are bacteria-produced proteins that can make certain antibiotics ineffective. It helps determine if a bacterial infection may be resistant to carbapenem antibiotics, which are used for serious infections.

Why This Test Might Be Ordered
Your healthcare provider may order this test if you have a suspected infection caused by bacteria that could produce carbapenemases, especially if you’ve been exposed to carbapenem antibiotics. It’s also used in monitoring patients with known or suspected infections involving resistant bacteria, such as those in intensive care units or with healthcare-associated infections.
How the Test Works
The test uses a rapid immunoassay (a type of antibody test) on a small sample of your serum or plasma. It detects specific proteins (carbapenemases) that bacteria produce to break down carbapenem antibiotics. Results are typically available within 30 minutes.
Sample Collection and Preparation
A blood sample is drawn from a vein, usually in your arm. The blood is processed to separate the serum or plasma, which is then tested. No special preparation is needed, but fasting may not be required unless specified by your provider.
What to Expect During and After the Test
You’ll likely feel minor discomfort from the needle insertion, but most people tolerate it well. After the test, you may experience a small bruise or swelling at the injection site, which usually fades within a few days. No special follow-up is needed unless your provider advises otherwise.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate the presence of carbapenemase-producing bacteria, which can lead to infections resistant to carbapenem antibiotics. This information is critical for guiding appropriate antibiotic treatment, reducing the risk of further spread of resistant bacteria, and preventing unnecessary use of ineffective antibiotics. Early identification helps prevent complications and ensures you receive the most effective therapy.
