Overview

LTA use in suspected PFD warrants specialist referral; leaves open standardization and point-of-care alternatives.

Structured PICO

P
Population
Patients with suspected platelet function disorders (thrombocytopathy)
I
Intervention
Light transmission aggregometry (LTA)
C
Comparator
Alternative diagnostic methods (multiple electrode platelet aggregometry, flow cytometry, molecular tests)
O
Outcome
Diagnosis of platelet function disorders

Light transmission aggregometry remains the gold standard for diagnosing platelet function disorders, with recent automation improving its clinical accessibility despite inherent methodological limitations.

Limitations

  • Susceptible to pre-analytical, analytical, and interpretation errors
  • Lack of standardization
  • Time-consuming procedure
  • Requires significant blood volume
  • Available only in specialized hemostasis laboratories
