Specimen collecting, processing and analytical assembly
First Claim
1. A specimen collecting and analytical assembly comprising in combination:
- a. a one piece barrel container having an open top and a capillary tube with an open end, with a chamber disposed there between,b. the chamber having a support means at the distal end and a single disc-shaped filter membrane placed at the proximal end of the chamber, so that the chamber portion below the filter membrane is narrowed to a smaller diameter and extended in the shape of a capillary tube,c. said capillary tube being designed to draw a sample up to 2000 μ
l,d. said capillary tube being volumetrically graduated externally with specific color markings, and internally coated with an agent including a buffer, anticoagulant, detergent, stabilizer or a preservative, ande. wherein the top of the barrel houses a vial containing a suitable reagent packed under vacuum therein.

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.
