TEST STRIP FOR QUANTIFICATIONALLY DETECTING MARKER CYFRA21-1 AND PREPARATION METHOD THEREFOR AND DETECTION METHOD THEREOF

摘要

A test strip for quantificationally detecting a marker cyfra21-1 and a preparation method therefor and a detection method thereof. The test strip comprises: a sample pad (2) which is coated with a processing liquid, a combination pad (3) which is coated with a near infrared fluorescent nanoparticle-marked anti-cyfra21-1 first antibody, a nitrocellulose film (4) which is provided with a detecting band (5) formed by an anti-cyfra21-1 second antibody and a quality control band (6) formed by a goat-anti-mouse polyclonal antibody, and a water absorbing pad (7). According to the test strip for quantificationally detecting a marker cyfra21-1 and the preparation method therefor and the detection method thereof, the cyfra21-1 in urea is quantificationally detected; the sensitivity is high; the specificity is high; the test strip can be used for early detection and recurrence detection of the carcinoma of urinary bladder; urea is directly dropped on a test strip for implementing quick detection; in addition, the test strip is simple to prepare and can be massively produced; the costs are low; the detection by the test strip is quick; both time and labor are saved; the test strip is widely applicable to the clinic.
