Purpose of the Test

The Bed Sore bacterial culture and sensitivity (C/S) test with Gram stain are ordered to diagnose and identify the bacteria causing a wound infection, specifically a pressure ulcer or bed sore.

When this test is required

This test is typically requested when a patient has a bed sore that is not healing properly or appears to be worsening, which may indicate a bacterial infection. Symptoms of infection may include redness, swelling, warmth, pain, or discharge from the sore.

What the Test Detects

The test being referred to is a bacterial culture and sensitivity (C/S) test for aerobic bacteria, along with a Gram stain, performed on a sample taken from a bed sore.

Preparation for the Test

There is usually no special preparation needed for the test. However, it is important to inform the healthcare provider about any antibiotics that the person is currently taking, as this may affect the test results. In summary, the Bed Sore bacterial culture and sensitivity (C/S) test with Gram stain is ordered to identify the bacteria causing a wound infection, and it is typically performed when a person develops a bed sore or pressure ulcer. A sample is taken from the affected area, and no special preparation is usually required.

Sample Requirements

The sample required for the test is usually taken from the bed sore or pressure ulcer site. A healthcare provider will use a sterile swab to collect a sample of the wound’s discharge, tissue, or fluid. The sample is then sent to a laboratory for analysis.

Additional Notes

It is important to note that this test only identifies bacterial infections and is not useful for identifying viral or fungal infections. Additionally, the test results may take several days to become available, during which time the patient may need to begin empiric antibiotic therapy to control the infection. Finally, while this test is useful in guiding antibiotic selection, the physician should also take into consideration the patient’s medical history, drug allergies, and other factors when making treatment decisions.
