There are several types of laboratory tests that may be used to diagnose and monitor wound infections. Some common tests include:

1. Culture and sensitivity test: This test involves taking a sample of the wound secretions or tissue and growing it in a laboratory to identify the type of bacteria present and determine which antibiotics are effective in treating the infection. The test is performed using a code from the Current Procedural Terminology (CPT) code system, such as 87070 (Bacteriology culture and/or sensitivity, each isolate).
2. White blood cell count (WBC): This test measures the number of white blood cells in the body. A high WBC count may be a sign of infection. The test is performed using a CPT code, such as 85025 (Complete blood count with differential WBC).
3. C-reactive protein (CRP) test: This test measures the level of CRP in the blood. CRP is a protein produced by the liver that increases in response to inflammation. A high CRP level may indicate an infection or other type of inflammation. The test is performed using a CPT code, such as 86140 (C-reactive protein, quantitative).
4. Erythrocyte sedimentation rate (ESR) test: This test measures the speed at which red blood cells settle to the bottom of a tube in a laboratory. A high ESR may indicate inflammation or infection. The test is performed using a CPT code, such as 85651 (Erythrocyte sedimentation rate).

It is important to note that these tests are just a few examples of the many different types of laboratory tests that may be used to diagnose and monitor wound infections. The specific tests that are ordered will depend on the specific needs of the patient and the characteristics of the wound. It is always best to consult with a healthcare professional for advice on the most appropriate tests for a particular situation.

Culture and sensitivity test for infections

A culture and sensitivity test is a laboratory test that is used to identify the type of bacteria present in a wound and determine which antibiotics are effective in treating the infection. This test is typically ordered when a wound infection is suspected or when a wound is not responding to treatment as expected.

To perform a culture and sensitivity test, a sample of the wound secretions or tissue is collected and sent to a laboratory for analysis. The sample is placed in a special medium that allows the bacteria to grow. Once the bacteria have grown, they are identified and tested to see which antibiotics are effective in killing them. The results of the test are used to guide the selection of the most appropriate antibiotic treatment for the infection.

It is important to note that a culture and sensitivity test is just one of many different types of tests that may be used to diagnose and manage wound infections. The specific tests that are ordered will depend on the specific needs of the patient and the characteristics of the wound. It is always best to consult with a healthcare professional for advice on the most appropriate tests and treatments for a particular situation.
