Abstract
The stability of albumin, protein HC, immunoglobulin G, κ- and λ-chain immunoreactivity, orosomucoid and α1 -antitrypsin in urine stored at -20°C for up to 24 months was investigated. Significant decreases of the median concentration values for protein HC, IgG and α1-antitrypsin were observed for native urine. Addition to urine of a preservative solution containing benzamidinium chloride, EDTA, tris(hydroxymethyl)-aminomethane and azide prevented the decreases of the concentration values for protein HC and IgG but not for α1-antitrypsin. The median concentration values for albumin, orosomucoid and κ-and λ-chain immunoreactivity did not change significantly upon storage of native urine, nor for urine with the preservative solution.
