Key result
The 96-well Optimul assay showed 82% concordance with light transmission aggregometry (κ = 0.62, P < .0001) and demonstrated high sensitivity (94%) for detecting mild platelet defects.
Why the study?
Does the Optimul assay accurately characterize platelet defects compared to light transmission aggregometry in patients with bleeding and healthy volunteers?
Observational (n=125)
Does the Optimul assay accurately characterize platelet defects compared to light transmission aggregometry in patients with bleeding and healthy volunteers?
Effect estimate: κ = 0.62
p-value: p=<.0001
The Optimul assay is a sensitive, high-throughput screening option for detecting mild platelet defects in patients with bleeding symptoms, performing comparably to or better than LTA.
No takes yet. Share an insight, caveat, or question.
May support Optimul as high-throughput screen for mild platelet defects; leaves open prospective validation before clinical adoption.
Lordkipanidzé et al. (2014) conducted an observational in Bleeding of unknown origin (n=125). Optimul assay vs. Light transmission aggregometry (LTA) was evaluated on Concordance between Optimul and LTA assays (κ = 0.62, p=<.0001). The 96-well Optimul assay showed 82% concordance with light transmission aggregometry (κ = 0.62, P < .0001) and demonstrated high sensitivity (94%) for detecting mild platelet defects.
