Why the study?
Does an ultrafiltration technique provide comparable HDL cholesterol quantification to dilution or ultracentrifugation methods in turbid heparin-manganese supernates?

Ultrafiltration is a convenient and valid alternative to dilution or ultracentrifugation for quantifying HDL cholesterol in turbid samples.
No takes yet. Share an insight, caveat, or question.
Ultrafiltration may introduce small positive bias in HDL values; leaves open need for outcome-linked standardization across methods.
Warnick et al. (1981) studied this question.
