Double Lumen Tube for Bacterial C/S (Aerobic) with Gram Stain

Specimen Required

Double Lumen

Fasting Required

Purpose of the Test

The test is used to determine the type of bacteria causing the infection and to determine the best antibiotic treatment.

When this test is required

This test is typically requested when a patient is suspected to have a bacterial respiratory infection, such as pneumonia or bronchitis, and when previous treatments have been unsuccessful. It may also be used to monitor the effectiveness of current antibiotic treatment and adjust treatment as necessary.

What the Test Detects

A double lumen tube for bacterial C/S (aerobic) with gram stain is a medical test used to identify and isolate bacterial infections in a patient’s respiratory tract. This test is conducted by collecting a sample of the patient’s respiratory secretions through the use of a double lumen tube. One lumen is used for ventilation, and the other is used to collect the sample.

Preparation for the Test

Before the test, the patient should not eat or drink anything for several hours to reduce the risk of vomiting during the procedure. The patient should also inform the healthcare provider of any medications they are taking, as some medications may need to be stopped temporarily before the test.

Sample Requirements

The test requires a sample of respiratory secretions, which is collected using a double lumen tube. The tube is inserted through the nose or mouth and into the lungs, where it is used to collect a sample of the secretions.

Additional Notes

It is important to note that this test may be uncomfortable for the patient and carries a small risk of complications, such as bleeding or infection. It is also important to follow proper infection control procedures to prevent the spread of infection during the collection and transportation of the sample.
