Description
PSA testing measures prostate health to help detect potential issues like enlargement or cancer, often recommended for men over 50 or with urinary symptoms; costs ¥30–70 at partner hospitals in China, with ChinaMedicalHub assisting with booking and interpreter support.
Main Uses
The primary purpose of the PSA test is to screen for prostate cancer, especially in men over 50 years old. It is also used to monitor the effectiveness of treatment in patients already diagnosed with prostate cancer. Additionally, it can help in assessing the risk of developing prostate cancer and in making decisions about further diagnostic procedures such as biopsies.
Normal Range
The normal range for Prostate-Specific Antigen (PSA) is generally less than 4.0 ng/mL, though some guidelines suggest that levels below 2.5 ng/mL are considered very low risk. It's important to note that the interpretation of PSA levels can vary based on age and other factors.
Low Values - Possible Causes
Low PSA values are typically not a cause for concern. However, in rare cases, they might be associated with: hypogonadism, certain medications (like finasteride or dutasteride), malnutrition, or overhydration.
High Values - Possible Causes
Elevated PSA levels can be caused by: prostate cancer, benign prostatic hyperplasia (BPH), prostatitis, recent ejaculation, or a digital rectal exam (DRE).
