B&B Bio Influenza A/B RNA detection by RT-PCR Kit

What it detects

• Detects viral RNA from influenza A and influenza B viruses
• Can differentiate between type A and type B infections (important clinically)

These are molecular diagnostic tests (NAAT / RT-PCR), widely used for accurate flu diagnosis.

How it works (RT-PCR)

• Reverse transcription (RT): viral RNA → DNA
• PCR amplification: detects specific influenza gene targets

Results indicate:

• Influenza A positive
• Influenza B positive
• Negative (no influenza RNA detected)

Some assays can further identify influenza A subtypes (e.g., H1N1, H3N2).

Specimen type

• Nasopharyngeal (NP) swab

What the test is used for

Primary purpose: Diagnosis of influenza infection

• Confirms active infection with influenza A or B

Key clinical uses

• Evaluate patients with flu-like symptoms (fever, cough, sore throat)
• Distinguish flu from other respiratory infections (e.g., COVID-19)
• Guide antiviral treatment decisions
• Support infection control during flu season

These tests are highly accurate, with high sensitivity and specificity (~90–95%).
