Abstract
A method of determining the stage (gestation) of a pregnancy—comprising the steps of quantifying the amount of the hormone hPL or a fragment thereof in a body fluid sample derived from a human female selected from a blood, plasma, serum and/or urine sample, and establishing the stage of pregnancy corresponding thereto. The disclosure also extends to a device adapted to detect the levels/amount of hPL or a fragment thereof in a body fluid sample, derived from a human female, selected from a blood, plasma, serum and/or urine sample, for establishing the stage of pregnancy.
Claims8
A disposable immunoassay device-comprising:
- a housing comprising:
- a) a test strip comprising:
- a sampling portion;
- a test zone in fluid communication with the sampling portion, the test zone comprising at least one anti-hPL antibodies or antigen binding fragments thereof;
- the at least one anti-hPL antibodies is immobilized in the test zone;
- the test zone further comprising at least one labeled anti-hPL antibodies or antigen binding fragments thereof wherein the label comprises a colored label or a fluorescent label,
- b. an electrical power source,
- c. a detector aligned with the test zone for detecting a property of the test zone which is affected by the colored label or the fluorescent label and producing a signal having a magnitude which is proportional to an amount of the colored label or the fluorescent label in the test zone, thereby quantifying the hormone analyte in a urine sample;
- and
- d. a display providing information related to the stage of pregnancy as a number of a given week selected from the group consisting of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17.18, 19, 20, 21, 22, 23 and 24, or range of weeks,
- wherein the range is selected from 8 to 24 weeks, wherein the number displayed is correlated to the signal produced by the detector.
