Stability of urinary HVA and VMA on filter paper.
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.
