Hi ElMaestro,

❝ ❝ Keep the number of time points equal and give the sequence of samples (1, 2, …, n) and not the time points themselves (t₁, t₂, …, t_n) on the vials’ label.

❝

❝ […] I guess one could pad the series holding only 20 samples with a sample 21 and 22 based on extracted un-spiked plasma. That would kind of win the olympic gold, wouldn't it?

Perhaps silver.

❝ The analyst will presumably be able to tell nothing about the nature of samples due to just the number of samples per series […].

Evidently, my dear Dr Watson. But: Sooner or later a smart analyst would start to wonder why in one period the last two samples are always BLQ.
