Embodiment 1

[0017] Embodiment 1: Preparation of FT3 quantitative detection kit

[0018] (1) Anti-FT3 antibody-coated plate preparation

[0019] a. Coating: Take 1mol / L Na 2 HPO 4 77.4ml and 1mol / L NaH 2 PO 4 22.6ml and mix well, add deionized water to 1000ml to form a 10-fold coating solution, dilute ten times before use, add an appropriate amount of anti-FT3 monoclonal antibody (purchased from fitzgerald) and mix well, then add to the wells of the microplate medium, 100μl / well, 4°C for 16 hours;

[0020] b. Sealing: Discard the coating solution, pat dry on absorbent paper, add 3% BSA and 0.05% preservative (Proclin TM 300) of phosphate buffer (pH 7.4), 200 μl / well, 37 ° C for 2 hours;

[0021] c. Seal the bag: Discard the sealing solution, pat it dry on absorbent paper, pump it in a vacuum oven for 5 hours at room temperature, immediately vacuum seal the bag, check for air leakage, and re-seal the bag if there is a label. Store at 2-8°C.

Abstract

The invention discloses a chemiluminescence quantitative detection kit for free triiodothyronine. The kit comprises a free triiodothyronine detection reaction plate, an enzyme conjugate, a luminescent substrate, a calibrator, a quality control material and washing concentrate, wherein the reaction plate is coated with a free triiodothyronine antibody. The kit can specifically and quantitatively detect the content of the free triiodothyronine in patient serum, and is used for the auxiliary diagnosis of thyroid dysfunction diseases. Compared with the conventional enzyme linked immunosorbent assay (ELISA) technology, the chemiluminescence immunoassay keeps high specificity of the ELISA technology, stability and reliability of a detection result, and convenience of operation, and can improve detection sensitivity simultaneously.

Description

technical field [0001] The invention belongs to the technical field of in vitro clinical testing and chemiluminescence immunoassay, and specifically relates to a chemiluminescent quantitative detection kit for free triiodothyronine (FT3) and related preparation methods and usage methods. Background technique [0002] Thyroid dysfunction is the most common endocrine disease, and it is still easily underdiagnosed. According to the census of 46,000 people in 11 cities in the United States, it is found that about 11% of the people have various thyroid dysfunctions that have not been diagnosed. Thyroid dysfunction can be divided into hyperthyroidism (referred to as hyperthyroidism) and hypothyroidism (hypothyroidism, referred to as hypothyroidism). [0003] Thyroid hormone is the collective name for thyroxine (T4) and triiodothyronine (3,5,3'-triiodothyronine, T3), both of which are iodine-containing derivatives of tyrosine. More than 99% of T3 and T4 in plasma are reversibly b...
