Prostate Testing Example Results

Below you will find prostate testing sample results with explanations, relevant ranges, and potential interpretations. Note that there are often minor differences in the reference ranges of the prostate tests depending on the laboratory that performs the analysis. Linked to the corresponding illustrative sections below, result examples include:

Prostate-Specific Antigen (PSA) Results

The Prostate Specific Antigen (PSA) blood test measures the level of PSA in a man's blood. PSA levels under 4 ng/mL are generally normal for a healthy male. According to published studies, PSA levels between 4 and 10 result in a 25% chance of prostate cancer and a PSA result greater than 10 increases the risk of cancer to 67%. Rising levels of PSA over time are highly indicative of prostate cancer and consequently periodic testing is recommended.

Following is a sample of the results of the PSA blood test. The reference interval indicates the normal ranges and the flag indicates a result outside of those ranges.

LabCorp Example

Prostate-Specific Antigen (PSA) - LabCorp

PSA reference range:: 0.0 to 4.0 ng/mL

Quest Diagnostics Example

Prostate-Specific Antigen (PSA) - QuestPSA reference range: < or = to 4.0 ng/mL

Prostate-Specific Antigen (PSA), Free:Total Ratio Results

The Prostate Specific Antigen (PSA) Free and Total blood test measures the level of PSA and Free PSA in a man's blood. PSA levels under 4 ng/mL are generally normal for a healthy male. According to published studies, PSA levels between 4 and 10 result in a 25% chance of prostate cancer and a PSA result greater than 10 increases the risk of cancer to 67%. The Free PSA blood test measures the percentage of unbound PSA and the free:total PSA ratio helps to determine the relative risk of prostate cancer.

Following is a sample of the results of the PSA blood test. The reference interval indicates the normal ranges and the flag indicates a result outside of those ranges.

LabCorp Example

Prostate-Specific Antigen (PSA) Free and Total Ratio - LabCorp

PSA reference range: 0.0 to 4.0 ng/mL; PSA Free reference range: No reference range indicated. % Free PSA reference range: This percentage is calculated using the PSA result and PSA Free result. This percentage may then be used in the table below the results if indicated.

Quest Diagnostics Example

Prostate-Specific Antigen (PSA) Free and Total Ratio - Quest

PSA reference range: < or = to 4.0 ng/mL; PSA Free reference range: No reference range indicated. % Free PSA reference range: This percentage is calculated using the PSA result and the PSA Free result. The reference range for Quest is suggested at > 25%. This percentage may then be used in the table below the results if indicated.
