Digestive diseases are disorders of the digestive tract, which is sometimes called the gastrointestinal (GI) tract.
it include the Salmonella Typhi IgG&IgM, H.Pylori antibody test, H.Pylori antigen test, Rotavirus antigen test, Adenovirus antigen test.

In digestion, food and drink are broken down into small parts (called nutrients) that the body can absorb and use as energy and building blocks for cells.
The digestive tract is made up of the esophagus (food tube), stomach, large and small intestines, liver, pancreas, and the gallbladder.
A digestive disease is any health problem that occurs in the digestive tract. Conditions may range from mild to serious. Some common problems include heartburn, cancer, irritable bowel syndrome, and lactose intolerance.
200 tons of seafood cold storage refrigerant use precautions
The physical and chemical properties of various refrigerants vary, and there are different packs and pressures at different temperatures. At normal temperature, there is high pressure and low pressure. Generally, the refrigerants are stored in special steel cylinders. The cylinders used must be pressure tested regularly. For example, the cylinders that store ammonia are pre-tested at 60 atmospheres (gauge pressure) to store different refrigerants. The cylinders are also tested for different pressures, and the cylinders are painted in different colors to show the difference (ammonia bottle yellow, fluorine bottle silver gray), and indicate the abbreviation code and name to prevent misuse.
Cylinders storing different refrigerants cannot be exchanged for each other. The cylinders storing the refrigerant should not be exposed to the sun or near flames and high temperatures. Prevent cylinders from colliding with each other during transportation to avoid the risk of explosion. The control valve on the cylinder is usually protected by a cap or iron cover. After use, care should be taken to reinstall the removed cap or iron cover to prevent the control valve from being damaged by impact during handling.
When the refrigerant in the cylinder is used up, immediately close the control valve and put on the cap to avoid leakage of air or moisture. The refrigerant should avoid touching the skin and not touch the eyes. When it is found that there is a large amount of leakage of the refrigerant, the door and window must be opened, otherwise it will cause suffocation. When the refrigerant is pumped out of the system into the cylinder, the cylinder should be sufficiently cooled, and the refrigerant can only account for about 60% of the cylinder volume, so that it has a certain room for expansion at room temperature.
1. Using internal quality control samples:
Negative specificity: The results should all be negative when detecting 10 kits of HP negative quality
control samples.
Positive specificity: The results should all be positive when detecting 10 kits of HP positive quality
control samples.( Including strong, medium and weak positive samples)
Limit of detection: The results should all be positive when detecting diluted HP positive quality control
samples with the diluent rate at 1:8.
Repeatability: The results should be consistent and the coloration degree should be consistent when
detecting the precision control samples by 10 kits of the same batch.
2. Clinical trial results
A clinical evaluation was conducted on 1050 samples comparing the results obtained using the
Helicobacter Pylori Antibody Rapid Test Kit (Colloidal Gold) and other commercially available HP tests.
