Microalbumin detection freeze-drying reagent and reaction tube pre-storing freeze-drying reagent

Abstract

The invention provides a microalbumin detection freeze-drying reagent and a reaction tube pre-storing freeze-drying reagents, and relate to the technical field of medical examination. The reaction tube comprise a reaction tube body, the reaction tube body is of a cavity structure with an opening at one end, a water-soluble film is arranged in the cavity of the reaction tube body and divides the cavity in the reaction tube body into an upper cavity and a lower cavity, the lower cavity is filled with a freeze-drying reagent R1, the upper cavity is filled with a freeze-drying reagent R2, a detachable cover body is arranged on the reaction tube body at the top of the upper cavity, and when the cover body is not detached, the upper cavity is a closed cavity. The freeze-drying reagent preservation method is simple, the freeze-drying reagents pre-stored in the tube are reliable in performance and convenient to preserve and transport, the freeze-drying reagents in the reaction tube can be isolated from air, and thus the normal-temperature preservation of the freeze-drying reagents is convenient; and a coating film is torn off, and the freeze-drying reagents are detected on a machine, whichis very convenient and practical.

Description

technical field [0001] The invention relates to the technical field of medical testing, in particular to a freeze-dried reagent for detection of microalbumin and a reaction tube pre-stored with the freeze-dried reagent. Background technique [0002] The main hazards of diabetes are various acute and chronic complications, which are extremely harmful to the health of patients, and even cause life-threatening in severe cases. Among them, diabetic nephropathy (diabetic nephropathy, DN) is a common chronic complication of diabetes, and has also become an important cause of end-stage renal failure. Therefore, how to detect early diabetic nephropathy earlier, faster and more conveniently can prevent and treat diabetic kidney damage has great significance. This study takes diabetic nephropathy among the chronic complications of diabetes as the starting point. In clinical practice, urinary microalbumin indicators are usually used to monitor the occurrence of nephropathy. The detec...

Problems solved by technology

[0003] At present, microalbumin reagents are not stable when stored at room temperature, and can be stored for about 12 months at 2-8°C. Storing at -20°C will bring inconvenience to repeated freezing and thawing, and at the same time, it will have adverse effects on the performance of the reagent. However, the above problems can be well solved by using freeze-drying technology. Microalbumin reagents can be stored at 4°C or at room temperature for 2 years or even longer.

[0004] The storage method of microalbumin freeze-dried reagents mainly adopts the vacuum sealing method, which requires a high degree of vacuum, and the sealing process is complicated and inconvenient to operate.
