Question

The leukocyte alkaline phosphatase (LAP) stain on a patient gives the following results: 10(0), 48(1+), 38(2+), 3(3+), 1(4+) calculate the LAP score.

A. 62
B. 89
C. 103
D. 120

Answer 1

To calculate the LAP score, multiply the number of cells by the intensity of staining and sum the values. For the given LAP stain results, the calculated LAP score is 137, which doesn't match the provided multiple-choice answers, suggesting there might be an error.

Step-by-step explanation:

The question is asking to calculate the LAP score based on the results of the leukocyte alkaline phosphatase (LAP) stain. The LAP score is determined by multiplying the number of cells by the intensity of staining and adding the values together. The calculation based on the given results would be:
0 x 10 (for 0 intensity) + 1 x 48 (for 1+ intensity) + 2 x 38 (for 2+ intensity) + 3 x 3 (for 3+ intensity) + 4 x 1 (for 4+ intensity). The sum of these calculations gives us the LAP score: 0 + 48 + 76 + 9 + 4 = 137.

Since the LAP score of 137 is not among the answer choices, there may have been an error in the question or provided answer choices. It is important to double-check the scoring system used as it might vary, or there might be an error in the transcription of the results.
