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 °C or lower temperature. Storage at room temperature resulted...

Description
Summary: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 °C or lower temperature. Storage at room temperature resulted in degradation of the sample.
