Conjunctival Swab (Lt.) for AFB Price in Bangladesh

What is Conjunctival Swab (Lt.) for AFB?

A Conjunctival Swab (Lt.) for AFB (Acid-Fast Bacilli) is a diagnostic test used to detect the presence of Mycobacterium tuberculosis (the bacteria that causes tuberculosis) in the conjunctiva of the eye.

In this test, a swab is taken from the left eye's conjunctival sac, which is the mucous membrane lining the eyelid and covering the white part of the eye. The sample is then stained using the Ziehl-Neelsen stain, which helps visualize acid-fast bacilli under the microscope.

This test is typically performed when there is suspicion of ocular tuberculosis, which can cause eye inflammation, pain, and vision changes. It is especially useful in diagnosing TB when symptoms involve the eyes or if the patient has other risk factors for tuberculosis.

What to expect & how to prepare

A culture test looks for bacteria or other organisms in a sample and checks which antibiotics act against them. The sample is incubated in the laboratory, so this test needs more time than a routine blood report.

• Antibiotics: tell the laboratory if you have already started an antibiotic — it can change the result. Do not stop a prescribed medicine on your own.
• Sample collection: the correct sample and the way it is collected depend on the site being tested; the laboratory will instruct you or collect it for you.
• Timing: culture results take longer than routine tests because the organisms must grow first. Ask the laboratory when your report is expected.

Interpreted together with your symptoms — antibiotic choice should be made by a registered doctor, not from the report alone.
