weak d testing of which of the following is required?

Explanation:

Define Weak D antigen

Weak D is a variant of the RhD antigen characterized by reduced expression of D antigen on red blood cells.

Identify testing requirements

Weak D testing is required on all blood donors who initially test RhD-negative to prevent immunizing Rh-negative recipients.

Evaluate clinical recipients

For transfusion recipients, obstetric patients, and trauma patients, testing is not required; they are simply classified as Rh-negative.

Determine the correct option

Only blood donors must undergo mandatory weak D testing when typing as RhD-negative.

Answer:

• Obstetric patient
• Transfusion recipient
• Trauma patient
• Blood donor (Correct answer)
