A linearity standard includes a plurality of calibration solutions, each calibration solution having a different level of a reactant having a known response in a test strip and meter combination, and an electronic storage medium for storing calibration instructions and known responses for each solution of the plurality of calibration solutions.

Systems and methods for artificial test strip controls

A pinch wall and dam system for controlling fluid flow movement between a sample receiving pad and a test strip includes a sample receiving pad and a test strip in contact with the sample receiving pad. The fluid seeps more quickly under the first portion of the pinch wall than under the second portion of the pinch wall, such that the test strip becomes saturated prior to excess fluid being absorbed in the portion of the sample receiving pad away from the test strip such that the test strip does not become flooded, the portion of the sample receiving pad positioned away from the test strip being sufficiently sized to absorb the excess fluid. The pinch wall and dam system further includes a dam, sitting on top of the sample receiving pad, the dam preventing the backflow of fluid from an area near the first portion of the pinch wall.

Systems and methods for controlling excessive fluid flow in a cassette designed to receive a fluid sample

A system for determining a concentration of hemoglobin A1C includes a first lateral flow test strip, the first lateral flow test strip providing for a percent of HbA1C concentration; a second lateral flow test strip, the second lateral flow test strip providing for the total amount of hemoglobin; an antibody-microparticle stripe on each of the first and second lateral flow test strips; a conjugate stripe on each of the first and second lateral flow test strips; and a sample treatment buffer. The sample treatment buffer is strongly denaturing, and antibodies in the antibody-microparticle strip are covalently bound to microparticles.

Systems and methods for interference correction from hemoglobin variants

A system for determining a level of a lipid analyte corrected for hematocrit includes a test strip configured to receive a sample and a meter configured to receive the test strip. The system further includes circuitry and a microprocessor, the circuitry and microprocessor configured to read the test strip and the sample and determine a level of a lipid analyte and correct the level of the lipid analyte based on a hematocrit level of the sample.

Systems and methods for hematocrit correction in analyte test strips

A system for determining a level of Cotinine and Anabasine in a sample includes a test strip configured to receive a sample; and a meter configured to receive the test strip wherein the meter is configured to read the test strip and detect a level of Anabasine and Cotinine.
