Frequently Asked Questions (FAQs) for Buccal Smear for BARR Bodies Test:
Q1: Can a buccal smear for BARR bodies confirm infectious mononucleosis (mono)?
A: Identification of BARR bodies can support the diagnosis of infectious mononucleosis, but clinical evaluation and other tests are often needed for confirmation.
Q2: How accurate is the buccal smear for detecting EBV infections?
A: Buccal smears can identify BARR bodies, indicating EBV infection. However, false-negative results can occur, and other tests might be necessary for confirmation.
Q3: Is there a specific age group more prone to EBV infections detected by this test?
A: EBV infections, including those detected by buccal smears, can occur at any age but are more common in adolescents and young adults.
Q4: Can an EBV infection be treated based on buccal smear results alone?
A: Treatment decisions for EBV infections are typically based on overall clinical assessment rather than buccal smear results alone.
