Clinical decision support system

A system comprising:

• non-transitory machine-readable memory storing instructions that are executable;
• and
• one or more processing devices to execute the instructions to perform operations comprising:
• performing an analysis based on a clot curve for a test sample, the clot curve being based on an assay performed on the test sample, the analysis being performed in order to obtain one or more parameters associated with the clot curve, the one or more parameters comprising a D′-parameter, a D″-parameter, or both the D′-parameter and the D″-parameter, wherein the D′-parameter is a difference in absorbance between time points of maximum acceleration and acceleration zero-crossing of the clot curve, and the D″-parameter is a difference in absorbance between time points of maximum acceleration and a threshold of an absorbance travel of the clot curve;
• and
• analyzing the one or more parameters to determine whether there is an anticoagulant present in the test sample;
• and
• outputting information based on the determination.

A method performed by one or more processing devices, the method comprising:

• performing an analysis based on a clot curve for a test sample, the clot curving being based on an assay performed on the test sample, the analysis being performed in order to obtain one or more parameters associated with the clot curve, the one or more parameters being selected from a D′-parameter, a D″-parameter, or both the D′-parameter and the D″-parameter, wherein the D′-parameter is a difference in absorbance between time points of maximum acceleration and acceleration zero-crossing of the clot curve, and the D″-parameter is a difference in absorbance between time points of maximum acceleration and a threshold of an absorbance travel of the clot curve;
• and
• analyzing the one or more parameters to determine whether there is an anticoagulant present in the test sample;
• and
• outputting information based on the determination.
