Designed to resemble the appearance of patient samples, Para 4 is available in three clinically significant levels (low, normal and high) and has a long shelf life which reduces the number of shipments, associated costs and time spent performing lot-to-lot correlation. It is available in glass vials or in squeeze dropper vials.
