Testing prostate-specific antigen levels in capillary blood

Determination of Prostate-specific Antigen in Capillary Blood (PSA-Cap)

Heinrich-Heine University, Duesseldorf · NCT06626386

This study is testing whether blood samples taken from a finger prick can give the same results for prostate-specific antigen levels as traditional blood samples taken from a vein.

What this trial studies

The PSA-Cap study aims to compare the measurement of total prostate-specific antigen (PSA) in serum obtained from venipuncture with that from capillary blood samples. It involves collecting capillary blood droplets from patients during routine PSA testing and analyzing both sample types under various storage conditions. The study also assesses the stability of the samples over time and the impact of transportation on measurement accuracy. Anonymized patient samples are used to ensure confidentiality while comparing results.

Who should consider this trial

Good fit: Ideal candidates for this study are men aged 45 to 70 who are undergoing PSA testing for prostate cancer screening.

Not a fit: Patients who are unable to give informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive method for PSA testing, making prostate cancer screening more accessible.

How similar studies have performed: While similar studies have explored PSA testing methods, this specific approach of using capillary blood for PSA measurement is relatively novel.
