What the review establishes
The dated items received AI-assisted checks of their answer, distractors, source support, and applicability. This is not clinician certification or certification-body endorsement. The rest of the available pool does not carry a claim of complete independent clinical validation.
Corrected concepts receive new question IDs. The 555 recorded versions include saved historical items, so an updated key does not rewrite an earlier score. 22 corrected versions address concepts from 55 held IDs; 82 held IDs still lack a reviewed replacement.
Keep the exam maps separate
The timed practice mock uses NHA CPT's five scored-domain weights: 100 study items in two hours. NHA's official exam also has 20 pretest items. ASCP PBT study topics are mapped separately; its computer-adaptive examination behavior is not reproduced by this mock.
| NHA domain | Available | Mock items | With source notes |
|---|---|---|---|
| Routine Blood Collections | 164 | 28 | 8 |
| Safety and Compliance | 79 | 26 | 15 |
| Patient Preparation | 66 | 20 | 7 |
| Processing | 62 | 14 | 9 |
| Special Collections | 47 | 12 | 5 |
Each domain has enough available items to assemble the weighted mock without borrowing from another domain.
