Finasteride PSA Adjustment Calculator

Formula

The formula to calculate the Finasteride PSA Adjustment is:

$\text{Adjusted PSA} = \frac{\text{PSA}}{0.5}$

Where:

Adjusted PSA is the adjusted Prostate-Specific Antigen level after taking Finasteride
PSA is the original Prostate-Specific Antigen level before taking Finasteride

What is a Finasteride PSA Adjustment?

Finasteride PSA adjustment refers to the recalibration of Prostate-Specific Antigen (PSA) levels in men taking the drug Finasteride. Finasteride, a medication used to treat conditions like benign prostatic hyperplasia and male pattern baldness, can lower PSA levels by approximately 50%. Therefore, to accurately assess a man’s risk of prostate cancer while on this medication, doctors often double the PSA test results. This adjustment helps in providing a more accurate interpretation of PSA levels and potential prostate cancer risk.

Example Calculation

Let's assume the following value:

Original PSA Level = 4.0

Using the formula to calculate the Adjusted PSA Level:

$\text{Adjusted PSA} = \frac{4.0}{0.5} = 8.0$

The Adjusted PSA Level is 8.0.
