Abstract

The invention relates to a test strip for detecting human thyroglobulin, which comprises a bottom plate, and a sample pad, a colloidal gold combination pad, a nitrocellulose membrane and a water absorption pad which are arranged on the bottom plate and connected in sequence; a detection line is arranged on the nitrocellulose membrane; the colloidal gold combination pad contains colloidal gold particles labeled by a combined antibody; a capture antibody is anchored in the detection line, and the binding antibody and the capture antibody can specifically recognize and bind thyroglobulin and do not interfere with each other. The colloidal gold test strip provided by the invention is convenient and rapid to use, can complete a chromatographic reaction within 10 minutes, is used for quantitative detection, and helps a doctor to judge whether the Tg content in peripheral blood exceeds a normal value range or not within a short time. The semi-quantitative detection test strip can be used by a patient, and daily self-monitoring of the patient is facilitated. The bifunctional test strip can be used for removing test samples with Tg content in a normal range, so that the workload of clinical detection is greatly reduced.

Description

technical field

[0001] The invention belongs to the technical field of biomedical detection, and in particular relates to a colloidal gold test strip for detecting human thyroglobulin. Background technique

[0002] Thyroglobulin (Tg) is a glycoprotein secreted by thyroid follicular epithelial cells, with a molecular weight of about 660kD. play an important role in the biosynthesis of . In a healthy person, only a very small amount of Tg enters the blood circulation, and the recommended normal value of Tg is 3-40ng / ml. Some diseases such as differentiated thyroid cancer (DTC) can cause elevated Tg levels in peripheral blood. Therefore, Tg is a key serological indicator of DTC, which can assist in the initial diagnosis and diagnosis of DTC. Regular follow-up of Tg levels after treatment can assist in monitoring the prognosis and recurrence risk of DTC patients.

[0003] At present, there are some technical problems in the determination of Tg content. First of all, there a...
