Abstract
A specimen collecting, processing and analytical assembly, designed for testing small volumes of body fluids, substances and secretions, said assembly comprising a one piece barrel assembly with a volumetrically graduated capillary tube having an open end, and optionally coated internally with an anticoagulant, a stabilizer or a preservative. The barrel assembly includes a filter membrane fitted above the capillary end at the junction of the barrel assembly and the capillary tube, a support means at the barrel'"'"'s second open end, and an analytical testing means disposed there between. The invention also provides a sealed vial containing an analytical testing reagent, the vial being substantially airtight and sealed with a pierceable material, a first tip cap for closing the open end of the capillary tube, a second cap to close sealably the second open end of the barrel container and a lancet to induce capillary skin punctures.

13. A method of collecting a specimen of a fluid, said method comprising the steps of:
-
a. bringing into contact with a fluid specimen to be tested an open capillary tube end of a barrel container, b. drawing said specimen into said capillary tube end to scavenge the desired volume of specimen, c. mixing said fluid specimen with the agent coating the capillary tube; and
d. sealingly covering the open end of the capillary tube with a tip cap.

14. A method of collecting a specimen of a fluid, said method comprising the steps of:
-
a. bringing into contact with a fluid specimen to be tested an open capillary tube end of a barrel container, b. drawing said specimen into said capillary tube end to scavenge the desired volume of specimen, c. mixing said fluid specimen with the agent coating the capillary tube;
d. placing said capillary tube end into a vial containing an analytical reagent and forcing said reagent into said open end, e. mixing said fluid specimen with said reagent in said capillary tube end;
f. closing the top open end of the barrel container with a second cap, and g. inverting the barrel container to draw said fluid specimen and said reagent through said capillary tube and into said chamber whereby said fluid specimen and said reagent filter through a filter membrane and collect into the chamber of the barrel container, ready to be stored.
