ABSTRACT:
A medical specimen collection system includes a blood specimen collection subsystem including a blood specimen card. The blood specimen card comprises a blotter-type absorbent material with locations for receiving blood droplets. A humidity-indicating pouch comprising, for example, a cobalt chloride composition applied to blotter-type absorbent substrate is mounted on the blood specimen card in fluidic communication therewith. The humidity-indicating patch changes color in response to changing moisture levels. The blood specimen card must have less than a predetermined moisture content for processing of the samples thereon. The system can comprise a prepackaged kit which also includes a urine specimen collection subsystem and a labeling/mailing subsystem with adhesive labels and a mailing envelope. A medical specimen collection method includes the steps of obtaining blood and urine specimens, indicating a moisture content of a blood specimen card, drying the blood specimen card if necessary and mailing the collective specimens.
