Purpose of the Test

Vitreous Aspirate for Bacterial C/S (Aerobic) with Gram Stain is a diagnostic test used to identify and diagnose bacterial infections in the vitreous humor, which is the clear, gel-like substance that fills the space between the lens and the retina in the eye.

When this test is required

This test is typically requested by healthcare providers when a patient presents with symptoms of endophthalmitis, which is an inflammation of the interior of the eye that can be caused by a bacterial infection. Symptoms may include pain, redness, and decreased vision. It may also be ordered if a healthcare provider suspects that a patient has a bacterial infection in the eye.

Preparation for the Test

No special preparation is typically required for this test. However, patients should inform their healthcare provider of any medications or supplements they are taking, as some medications may interfere with the accuracy of the test results.

Additional Notes

It is important to note that this test should only be performed by a trained healthcare provider and is not recommended for self-diagnosis or self-treatment. Patients should also inform their healthcare provider of any allergies or sensitivities to antibiotics, as this information will be used to determine the most effective treatment. Patients should also follow their healthcare provider’s instructions for caring for their eye while awaiting the test results. In some cases, additional tests may be needed to further evaluate the underlying cause of the infection.
