Appendix F — Determining the Platelet Estimate Factor
Follow the procedure below to determine the PLT estimate factor.
1. Perform automated PLT counts with a cell counter on 30 consecutive blood
samples.
2. Prepare and stain one smear for each sample.
3. Perform PLT analyses on the system. Let the system calculate the average PLTs/
HPF values for each sample.
4. Divide the cell counter PLT value by the system average PLTs/HPF value for
each sample to get the conversion factors.
5. Add all 30 conversion factors and divide by 30 to get the PLT estimate factor.
6. Enter the PLT estimate factor in the PLT tab in Settings.
