Summary

Retesting blood donors with a second fingerstick for microhematocrit analysis significantly reduces deferrals. This method improves donor acceptance without compromising iron status, enhancing blood donation efficiency.

Area of Science:

  • Transfusion Medicine
  • Hematology
  • Blood Donation Screening

Background:

  • Blood donors failing the initial copper sulfate hemoglobin test are typically retested using microhematocrit.
  • Current practice often uses a second sample from the same finger puncture for microhematocrit, potentially affecting accuracy.

Purpose of the Study:

  • To investigate if using a second, fresh finger puncture for microhematocrit testing reduces donor deferrals.
  • To assess the iron status of donors accepted through the revised microhematocrit procedure.

Main Methods:

  • Studied 201 volunteer blood donors who initially failed the copper sulfate test.
  • Compared microhematocrit results from the original fingerstick versus a second, fresh finger puncture.
  • Analyzed complete blood count and iron status markers from venous blood samples.

Main Results:

  • Utilizing a fresh finger puncture for microhematocrit testing reduced the deferral rate by 46%.
  • The iron status of donors accepted based on the second puncture was comparable to those accepted initially.
  • No significant difference in iron status was observed between donors accepted by the original versus the second puncture method.

Conclusions:

  • A second fresh finger puncture for microhematocrit determination effectively decreases hematocrit-related deferrals.
  • This revised procedure increases donor acceptance without negatively impacting the iron status of newly accepted donors.
  • Implementing a second fingerstick offers a practical improvement for blood donor screening protocols.
