Question

part ii: blood typing & transfusions

1. identify the blood type of each sample given the test results.

+ = clumping - = no clumping
suspect 1: suspect 2: suspect 3: suspect 4:
blood type: _ blood type: _ blood type: _ blood type: _

Explanation:

Step1: Recall blood - typing rules

In blood typing, if there is clumping (\(+\)) with anti - A serum, the blood has A antigens. If there is clumping with anti - B serum, the blood has B antigens. If there is clumping with anti - Rh serum, the blood is Rh positive.

Step2: Analyze Suspect 1

For Suspect 1: There is clumping with anti - A and anti - Rh. So, the blood type is A positive (\(A^{+}\)).

Step3: Analyze Suspect 2

For Suspect 2: There is clumping with anti - Rh. So, the blood type is O positive (\(O^{+}\)).

Step4: Analyze Suspect 3

For Suspect 3: There is clumping with anti - A. So, the blood type is A negative (\(A^{-}\)).

Step5: Analyze Suspect 4

For Suspect 4: There is clumping with anti - B. So, the blood type is B negative (\(B^{-}\)).

Answer:

Suspect 1: \(A^{+}\), Suspect 2: \(O^{+}\), Suspect 3: \(A^{-}\), Suspect 4: \(B^{-}\)
