Abstract:
A prothrombin time reagent for determination of low molecular weight heparin in frsh whole blood and in anti-coagulant treated blood is provided. The reagent is composed of recombinant animal tissue factor, and a mixture of synthetic phospholipids, which mixture includes a phosphatidylalcohol. A formulation buffer which includes a sensitivity adjuster is used in formulating the reagent. The recombinant animal tissue factor includes rabbit brain. The synthetic phospholipids of the mixture include palmitoyloleoylphosphatidylcholine (POPC), palmitoyloleoyl-phosphatidylserine (POPS), and a phosphatidylalcohol. The phosphatidyl alcohol includes dioleoylphosphatidylethanol, dioleoylphosphatidylmethanol, dioleoylphosphatidylpropanol, dioleoylphosphatidylbutanol, and dioleoylphosphatidylinositol. The sensitivity adjuster included in the formulation buffer is γ-Cyclodextrin. The formulated reagent is air-dried and remains stable for at least 3 weeks at 37 C.

US Classification:
436 71, 422422
Abstract:
In one embodiment, a test strip for testing for cholesterol-related blood analytes in whole blood includes a red blood cell separation layer, the red blood cell separation layer separating red blood cells from a blood sample applied to the test strip as the blood sample flows downward through the red blood cell separation layer. The test strip further includes a reaction layer receiving the blood sample from the red blood cell separation layer, the reaction layer including POE-POP-POE block copolymer, a surfactant, and a reflectivity changing reactant, the POE-POP-POE block copolymers solubilizing essentially only non-LDL cholesterol analytes, the non-LDL cholesterol analytes reacting with the reflectivity changing reactant in order to change a reflectivity of the blood sample.
Reagent Cocktail Preparation For The Rapid Production Of Serum
A cocktail reagent preparation for the rapid production of serum contains thrombin, snake venom, and protamine sulfate. The preparation employs very small quantities of clot promoting substances which behave in a synergistic manner such that rapid clotting of highly heparinized blood is achieved without altering the chemical analysis of the blood enzymes, proteins, sugars, or electrolytes. Thus, clinicians who rely upon the results of such tests can more closely monitor organ and tissue function and adjust patient therapies accordingly.
Standard Whole Blood Composition For Determining The Potency Of Blood Clotting Inhibitory Substances
A standard whole blood composition is disclosed, which is useful as a pooled human hemostasis reference standard in blood coagulation assays including Activated Clotting Time (ACT), Whole Blood Prothrombin Time (WBPT), Whole Blood Activated Partial Thromboplastin Time (WBAPTT) and Whole Blood Thrombin time (WBTT). Also disclosed are methods for determining the human standardized potency of heparin and protamine.

Abstract:
An apparatus and method for performing a coagulation time test on a sample of blood wherein the blood is deposited in a fluid reservoir and disposable cuvette. Within the cuvette is formed a capillary conduit have at least one restricted region. The cuvette is inserted into a testing machine which engages the cuvette and draws blood from the fluid reservoir into the capillary conduit. The blood is then caused to reciprocally move within the capillary conduit whereby the blood is forced to traverse the restricted region. The testing machine measures the time required each time the blood is caused to traverse the restricted region. When a measured time is a predetermined percentage longer than an immediately preceding time, coagulation is considered to have occurred and the overall coagulation time is displayed to the operator.
