Abstract
The invention provides a method for measuring the amount of analyte in a sample of biological fluid using a simple low sample volume reagent test strip with a built in metering system. The test strip may include a microtitration zone to prevent oversampling and an integrated capillary to prevent problems associated with short sampling and act as means of absorbing the fluid sample. The test strip comprises a wicking layer and a reaction matrix embossed layer in the form of a pillow assembled into a microtitration pocket formed in the strip. The test strip is used in single use applications such as the determination of the concentration of glucose in blood.

A test strip comprising a wicking layer and a reaction matrix embossed layer in the form of a pillow assembled into a microtitration pocket formed in the strip, and a capillary tube having a collar protruding into engagement with the pillow.
A test strip comprising a wicking layer and a reaction matrix embossed layer in the form of a pillow assembled into a microtitration pocket formed in the strip, and a capillary tube constructed to hold a specific volume of the sample and release the specific volume sample into the pillow wherein the specific volume is approximately 3 .mu.L.
A test strip comprising:
- a support member having a pocket formed therein;
- an embossed test matrix layer containing a reagent, the embossed test matrix layer comprising collapsed areas having a void volume of approximately zero surrounding a small bibluous pillow, the pillow received within the pocket;
- a top layer connected to the support member;
- and
- a capillary tube in communication with the pocket constructed to transfer a sample having a specific volume to the pillow, wherein the specific volume is approximately 3 .mu.L.
