How much does it cost to test gastric cancer specimens

Gastric cancer is a disease that people are very familiar with but particularly troubled by. If this disease occurs, the patient's life and work will be greatly affected. No one wants to be entangled by this disease and wants to stay away from it. So how much does it cost to test gastric cancer specimens? Let's take a look at the following introduction.

Relevant experts said that the question of "how much does it cost to test gastric cancer specimens" cannot be generalized, because different testing methods cost different amounts, and the costs also vary depending on the hospital and region. The gastric cancer examination items are as follows:

1. Gastric juice analysis

Normal gastric juice is colorless or light yellow, with about 0-10U of free hydrochloric acid and about 10-50U of total acidity in every 100ml of gastric juice. Gastric cancer patients often have low gastric acid or no free acid. About 65% of gastric cancer patients show gastric acid deficiency, while 200%-25% of patients still show gastric acid deficiency after stimulation with pentagastrin. The degree of gastric acid deficiency is often proportional to the size of gastric cancer. The degree of gastric acid deficiency in invasive cancer and gastric cardia is more severe than that in pyloric cancer. When gastric cancer causes pyloric obstruction, a large amount of food residue can be found. If accompanied by bleeding, coffee-like liquid may appear, which is of certain significance for the diagnosis of gastric cancer.

2. Fecal occult blood test

Persistent positive fecal occult blood test is of reference value for the diagnosis of gastric cancer and can provide clues for the discovery of gastric cancer. The positive rate of fecal occult blood test in early superficial gastric cancer can reach 20%. As the disease progresses, its positive rate can reach more than 80%. Among them, the positive rate of gastric body cancer is the highest, followed by cardiac cancer.

3. Immunological diagnosis

There are many methods for examination, which have begun to be used clinically in China. Monoclonal antibodies produced by hybrid cell cancer cell lines established by cell fusion have been used in the diagnosis and treatment of tumors at home and abroad. The research on monoclonal antibodies for gastric cancer diagnosis started early, and some have been used clinically.

4. Serological diagnosis and body fluid diagnosis

Gastric cancer has tumor-related antigens, and monoclonal antibodies can be used to detect these related antigens. CEA, CA-19-9, CA-50, and CA-125, which have been widely used, have a positive rate of about 60% in gastric cancer. Generally, if serum CEA exceeds 50ng/ml (normal).

The above article talks about the knowledge about gastric cancer examination items. If everyone can know these, it will be a great help in facing the difficult problem of gastric cancer in the future.
