Cumulative distribution functions (CDF) of (A) blood and (B) DLA samples with different collection to prep intervals. (A) The cumulative distribution functions of samples with one, two, three, and four+ days (d) between blood draw and sample preparation show a clear increase in cell density for time intervals of more than one day in (A) whole blood and (B) DLA samples. While a dependence of the number of events on the time from sample collection to sample preparation may also be observed in DLA samples, the difference is less pronounced than in blood.
