Patent ID: 8101415

Claim:
A method of adjusting a final reflectance signal value measured on a lateral flow assay test strip, comprising: measuring a series of reflectance signal values at a test site while performing a lateral flow assay reaction on a test strip; determining an extreme reflectance signal value representing the minimum reflectance signal value at the test site; determining an interim reflectance signal value, wherein the interim reflectance signal value is measured at the test site a pre-determined time period after the extreme reflectance signal value is measured; determining a final reflectance signal value at the test site after the interim reflectance signal value is determined; pre-determining a relationship between the interim reflectance signal value and the final reflectance signal value for the manufacturing lot from which the test strip has been made; adjusting the final reflectance signal value based upon the interim reflectance signal value and the pre-determined relationship between the interim reflectance signal value and the final reflectance signal value for the manufacturing lot from which the test strip has been made; wherein the step of adjusting the final reflectance signal value is conducted after the step of determining a final reflectance signal value.
