Claim:
1. A method of adjusting a final signal value measured on a lateral flow assay test strip, comprising: measuring signal values, the signal values resulting from optical analysis of a test strip with a meter wherein the meter measures the signal values, while performing a lateral flow assay reaction on the test strip, each of the signal values representative of an optical property of the lateral flow assay test strip at a point in time, the signal values measured over a time period during which the lateral flow assay test strip is tested; determining a minimum signal value using the meter, the meter configured to perform the determining of the minimum signal value and including instructions that the meter executes, the instructions stored in a computer readable medium, wherein the minimum signal value is the minimum measured value of reflectance measurements of the signal values; determining the time at which the minimum signal value is measured; determining a final signal value, wherein the minimum signal value and the final signal value are not the same using the meter, the meter configured to perform the determining of the time and the final signal value and including instructions that the meter executes, the instructions stored in a computer readable medium; and adjusting the final signal value using the meter to account for differences in a lot of test strips from which the lateral flow assay test strip originates as compared to an expected test strip, the lot of test strips from the same manufacturing lot, the meter configured to perform the adjusting of the final signal and including instructions that the meter executes, the instructions stored in a computer readable medium, based upon the time at which the minimum signal value is measured compared to an expected time at which minimum signal values are reached, wherein the final signal value is decreased when the minimum signal value is measured early as compared to the expected time.
