The worklistAbout 20 to 30 minutes

  • The Microscope worklist

    The learner picks a flagged CBC and works it guided or independently. Each attempt draws its own case and photographs, so learners do different cases.

Study a patternAbout 10 minutes

Teaching slides with photographs and a CBC. Nothing is scored.

What learners practice

  • Read an analyzer run and decide whether the CBC needs a smear review.
  • Identify 100 white cells from photographs and build the differential.
  • Correct the white count for nucleated red cells.
  • Apply the path review criteria and verify the report.

Assignment text

Open the Microscope worklist and complete one differential in independent mode. When the Verification sheet appears, choose Print record and hand in the printed record. Be ready to explain why the CBC needed a smear and which path review criteria your count met.

What the record shows

  • The case accession, the mode and the smear decision
  • The learner's call on each cell beside the reference, and the finished differential
  • The corrected white count when nucleated red cells were counted
  • The path review criteria marked and the verified report

The record stays with the learner until they hand it in. A finished record never changes, so printing it again gives the same page.

How it's scored
  • Scored in parts, with no single total: the smear decision, cell calls right out of the total, differential classes in range, findings, the corrected white count and the path review criteria.
  • Guided scores use each cell's first call. A CBC released from the analyzer is scored on its smear decision alone.
Accessibility
  • Every control can be reached with Tab and used with Enter or Space.
  • Every counter key also has a keyboard key; Shortcuts in the lab bar lists them.
  • Identifying cells from photographs is a visual task. During the count, image descriptions give the cell number without its classification.
  • Interface changes follow the site's short, steady timing, and they are instant when the device asks for reduced motion.
