What is the purpose of this test?
TheProstate-specific Antigen (PSA) Blood Test, Ultrasensitive is a highly sensitive laboratory test that measures very low levels of PSA, a protein produced by both healthy and cancerous cells in the prostate gland. This ultrasensitive PSA test is especially useful for monitoring PSA levels after prostate cancer treatment, such as surgery or radiation. It can detect tiny changes in PSA that standard tests might miss, allowing doctors to identify potential cancer recurrence at a much earlier stage.
This test is also helpful for evaluating men at increased risk of prostate cancer due to age, family history, or elevated PSA in the past. It can provide baseline measurements for comparison over time and help assess the effectiveness of ongoing treatments. Because it can detect extremely low PSA levels, it is often used to guide decision-making after prostate cancer has been treated or removed. This test can be a vital part of a man’s long-term prostate health monitoring plan.
Who should get this test?
- Men who have been treated for prostate cancer and need ongoing monitoring
- Individuals with a history of elevated PSA results
- Men with a strong family history of prostate cancer
- Those undergoing hormone or radiation therapy for prostate conditions
- Men participating in active surveillance for slow-growing prostate cancer
- Individuals who want a baseline PSA level for future comparison
- Men concerned about subtle or recurring prostate symptoms
When should I order the Prostate-specific Antigen (PSA) Blood Test, Ultrasensitive?
Individuals may consider ordering this test if they have symptoms or exposure concerns related to prostate health or a history of prostate cancer.
