Stability of urinary HVA and VMA on filter paper

Early Hum Dev. 1997 Sep 19;49(2):149-52. doi: 10.1016/s0378-3782(97)01886-0.

Abstract

The study examined the stability of HVA and VMA in 1-ml aliquots of a single urine sample stored on filter paper at different temperatures for 2 years. The results showed that HVA and VMA were stable in dried filter paper when stored at 4 degrees C or lower temperature. Storage at room temperature resulted in degradation of the sample.
