The invention discloses a colloidal gold detection card special for detecting lactoferrin in tears. The colloidal gold detection card comprises a shell of a hollow structure. Partitions are arranged in the shell. The interior of the shell are equally divided into 3-8 detecting chambers by the partitions. Slide rails are arranged on the inner walls on two sides of each detecting chamber. A movable base located between every two slide rails are slidably connected to the two slide rails. A testing strip is adhered to the outer wall of the top of each movable base, limit plates are fixedly connected to the outer walls on two sides of the testing strip, a retaining plate is fixedly connected between the limit plates, and a tear temporary storage tube is fixedly connected to one lateral wall, close to the testing strip, of the retaining plate. A first storage channel and a second storage channel are respectively formed in the top outer wall and the bottom outer wall of each detecting chamber, and a top cover and an L-shaped dustproof plate are respectively movably connected into the first storage channel and the second storage channel. The colloidal gold detection card is especially applicable to a testing environment with a large sample base.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a special colloidal gold detection card for detecting lactoferrin in tears. Background technique [0002] Lactoferrin is a glycosylated protein with broad-spectrum antimicrobial properties. Lactoferrin in tears is mainly secreted by the lacrimal gland, together with tear lysozyme, tear prealbumin, and a small amount of secreted immunoglobulin and growth factors, it constitutes the main component of the protein in tears and protects the ocular surface from foreign objects. Dry eye disease is a common disease. Clinical examinations for diagnosis of dry eye disease include tear secretion test, tear film break-up time, corneoconjunctival epithelial staining, imprint cytology examination, lysozyme content detection, lactoferrin content detection, etc. The content of lactoferrin in tears is relatively stable. The content of lactoferrin in normal tears is between 1.14 and 1.78g...
