Key result
Magnesium sulfate maintained stable platelet counts (201.1 × 10^9/L) and MPV (9.3 fL) over 3 hours with marginal cell swelling compared to EDTA, providing a reliable alternative for MPV measurement.

Absolute Event Rate: 201.1% vs 227.7%
Magnesium sulfate may offer a more reliable alternative to EDTA for in vitro anticoagulation when measuring mean platelet volume and assessing platelet activation.
Mannuß et al. (2016) studied Healthy volunteers (implied). Magnesium sulfate (MgSO4) vs. EDTA and citrate was evaluated on Mean impedance platelet counts (x 10^9/L). Magnesium sulfate maintained stable platelet counts (201.1 × 10^9/L) and MPV (9.3 fL) over 3 hours with marginal cell swelling compared to EDTA, providing a reliable alternative for MPV measurement.
