Haemophilus Influenzae Type B Antigen - Serum

This test is often recommended for individuals, especially children, who present symptoms indicative of a Hib infection such as fever, lethargy, vomiting, or signs of meningitis like severe headache, neck stiffness, sensitivity to light, and confusion.

The test requires a blood sample which is drawn from a vein in the arm. In the lab, the blood is processed to obtain the serum, which is then analyzed for the presence of Hib antigen.

No special preparation is required before this test.

A positive result means that Hib antigen is present in the serum, indicating an active or recent infection with Haemophilus influenzae type b. A negative result means no Hib antigen was detected, and it's unlikely that the person has a Hib infection.

Timing of the test in relation to when symptoms first appeared can affect the test results. Antibiotic treatment can also affect the results.

No, the test involves drawing blood which should be performed by a healthcare professional. Also, the analysis requires specialized equipment.

You should consult an infectious disease specialist or a pediatrician (for children) if your test results are abnormal.

Prompt diagnosis of a Hib infection can prevent severe complications such as meningitis or pneumonia. If you or your child are experiencing symptoms indicative of a Hib infection, it is essential to seek medical attention immediately. This test is a valuable tool that can assist in the early detection and treatment of Hib infections. It's important to remember that while the test can provide valuable information, the results should always be interpreted by a qualified healthcare professional in the context of your overall health status and clinical symptoms.
