H. Watanabe et al., PSA ASSAY OF DRIED BLOOD-SAMPLES FROM THE EAR LOBE ON A FILTER-PAPER WITH SPECIAL REFERENCE TO PROSTATIC MASS-SCREENING, The Prostate, 27(2), 1995, pp. 90-94
To eliminate complicated procedures for taking blood samples in the fi
eld work for prostatic mass screening, we developed a method for PSA t
esting using blood samples taken from the ear lobe and dried on a filt
er paper. The stability, the diagnostic efficacy, and the cost-benefit
effect of the method were confirmed in hospitalized patients, as well
as in subjects from our mass screening program. (C) 1995 Wiley-Liss,
