Description

Detection device for detecting ratio of fPSA and tPSA

Technical Field

The utility model relates to the technical field of medical detection, in particular to a detection device for detecting the ratio of fPSA and tPSA.

Background

Prostate cancer accounts for 10% -20% of all types of cancers in men, is the most common cancer in men, progresses slowly, and has a rapid increase in incidence in men older than 65 years, so that prostate cancer is the main cancer threatening the lives of men over 50 years old, and accounts for the second place of mortality in men in the western world. Epidemiological investigation shows that along with the improvement of the living standard of China, the incidence of prostate cancer is increasing day by day due to pollution and Western change of dietary structure, and a high importance of tumor clinic must be drawn. PSA testing is widely used to diagnose prostate cancer and is a good tumor marker, and the FDA in the united states has approved PSA testing as an indicator of screening men over 50 years old. PSA is a prostate specific antigen, fPSA is a free prostate specific antigen, and PSA enters the blood to bind with proteins mostly and fPSA is in a free state in a small part, the prostate specific antigen is an important indicator of prostate cancer.

fPSA/tPSA refers to the ratio of free prostate specific antigen to total prostate specific antigen, which is one term of blood testing, and normal values are typically greater than 0.16, commonly used to identify the presence of possible lesions in the prostate, such as tumors, etc., most studies have shown that fPSA is an effective method of increasing the detection rate of prostate cancer with tPSA levels in the gray area. When serum tPSA is between 4 and 10ng/ml, fPSA levels are inversely related to the incidence of prostate cancer. Studies have shown that if a patient has tPSA in the above range, fPSA/tPSA < 0.1, then the patient is up to 56% more likely to develop prostate cancer; in contrast, if fPSA/tPSA > 0.25, prostate cancer is only 8% likely. Domestic recommendation fPSA/tPSA > 0.16 as normal reference value (or critical value)
