A composite collection device suitable for the collection of fluid samples is disclosed. The device is suitable for the collection of a multitude of fluid samples, including biological fluids like blood, urine, saliva, plasma specimens for subsequent determination of analytes contained therein. An accurate volume fluid collection card system with a single or multiplicity of cells comprises three strata, a middle absorbent stratum, layered between an impermeable cover stratum containing at least one aperture and a transparent stratum containing indicia. The aperture in the impermeable cover stratum directs the fluid onto the middle absorbent. The middle absorbent stratum contains no alterations. The transparent stratum contains indicia that indicate the extent of the absorption of the fluid.

1. A collection card system comprising: a) a cover, wherein said cover has at least one debossed funneling aperture having an inner opening slightly smaller than the outer opening that directs a sample having a measurable volume onto b);b) an unaltered absorbent material layered beneath said cover;
1. A collection card system comprising: a) a cover, wherein said cover has at least one debossed funneling aperture having an inner opening slightly smaller than the outer opening that directs a sample having a measurable volume onto b);b) an unaltered absorbent material layered beneath said cover; andc) a base layered beneath the entirety of the absorbent material, which is impermeable to the sample but permits drying. 2. The collection card system of claim 1, wherein the cover is comprised of impermeable material. 3. The collection card system of claim 1, wherein the cover has three apertures. 4. The collection card system of claim 1, wherein the base is transparent. 5. The collection card system of claim 1, wherein the base contains indicia corresponding to and aligned with the one or more aperture. 6. A method of collecting a sample for analyte evaluation comprising: a) collecting one or more sample specimen on a device comprising: i) a cover, wherein said cover has at least one debossed funneling aperture having an inner opening slightly smaller than the outer opening that directs the sample having a measurable volume onto b);ii) an unaltered absorbent material layered beneath said cover; andiii) a base layered beneath the entirety of said absorbent material, which is impermeable to the sample but permits drying. 7. The method of claim 6, wherein the cover is comprised of impermeable material. 8. The method of claim 6, wherein the cover has three apertures. 9. The method of claim 6, wherein the base is transparent. 10. The method of claim 6, wherein the base contains indicia corresponding to and aligned with the one or more aperture. 11. A device for collection of a bodily fluid sample having a measurable volume comprising at least three strata, wherein a first stratum provides one or more debossed funneling apertures having inner openings slightly smaller than the outer openings that direct for deposition of the sample and; a second stratum layered beneath the first stratum, the second stratum comprised of an unaltered absorbent material to collect the sample; and a third stratum layered beneath the entirety of the second stratum, the third stratum allowing for indication of volume of sample, which is impermeable to the sample but permits drying. 12. A card for the collection of a bodily fluid sample having a measurable volume comprising at least three strata, wherein a first stratum provides one or more debossed funneling apertures having inner openings slightly smaller than the outer openings that direct deposition of the sample; a second stratum layered beneath the first stratum, the second stratum comprised of an unaltered absorbent material to collect the sample; and a third stratum layered beneath the entirety of the second stratum, the third stratum allowing for indication of volume of sample, which is impermeable to the sample but permits drying; wherein the card comprises an indicator for assessing the volume of the sample, wherein the indicator does not impede the collection or analysis of the sample. 13. A system for sample collection of a sample having measurable volume comprising: a) a first layer of impermeable material, wherein the first layer provides one or more debossed funneling apertures having inner openings slightly smaller than the outer openings that direct for deposition of the sample;b) a second layer of unaltered absorbent material, wherein the second layer provides for collection of the sample; andc) a third layer of transparent material layered beneath the entirety of the second layer, which is impermeable to the sample but permits drying, wherein the third layer provides for assessing an adequate amount of sample absorbed on the second layer. 14. A device for the collection of a sample comprising one or more debossed funneling apertures having an inner opening slightly smaller than the outer opening that directs deposition of sample having a measurable volume; an unaltered substrate for maintaining the sample; a visual indicator for assessing the volume of the sample; and a transparent layer beneath the entirety of the substrate, which is impermeable to the sample but permits drying.
