The r-sperm protein assay (r-sm) is a specific protein associated with the prostate in semen and was used for forensic identification in early years. It is now used for specific determination of prostate cancer. The positive rate of r-SM in prostate cancer patients was 68%, and the serum r-sm level was related to the condition. The more severe the disease, the higher the level. The positive rate of prostatic hypertrophy is only 1%, and the positive rate of malignant tumors other than genitourinary system is zero.

Basic Information

Specialist classification: male examination check classification: semen and prostatic fluid examination

Applicable gender: whether the male is fasting: not fasting

Analysis results:

Below normal:
No clinical significance.

Normal value:
Male: 0-296μg/L

Above normal:
Prompt for prostate cancer.

negative:
normal.

Positive:
The positive rate of r-SM in prostate cancer patients was 68%, and the serum r-sm level was related to the condition. The more severe the disease, the higher the level. The positive rate of prostatic hypertrophy is only 1%, and the positive rate of malignant tumors other than genitourinary system is zero.

Tips: Before leaving semen, the patient should stop sexual intercourse for 4 to 7 days. Testosterone propionate, testosterone phenylacetate, and nantrolone phenylpropionate could not be used 1 week before the test. Normal value

Male: <296μg/L.

Clinical significance

The positive rate of r-SM in prostate cancer patients was 68%, and the serum r-sm level was related to the condition. The more severe the disease, the higher the level. The positive rate of prostatic hypertrophy is only 1%, and the positive rate of malignant tumors other than genitourinary system is zero.

Positive results may be diseases: precautions for prostate cancer

Before leaving semen, the patient should stop sexual intercourse for 4 to 7 days. Testosterone propionate, testosterone phenylacetate, and nantrolone phenylpropionate could not be used 1 week before the test.

Inspection process

The analyte reacts with a specific enzyme label, and finally develops color through the substrate, and the absorbance is related to the concentration of the elastase in the seminal plasma sample.

Not suitable for the crowd

There are no taboos.
