A method for isolating urea and removing CO2 from plasma samples, comprising the following steps: a) providing a plasma sample; b) adding an acid so as to partially remove CO2; c) lyophilizing the sample so as to further remove CO2 and obtain a dried sample; and d) redissolving the dried sample and neutralizing to a pH value of 4 to 7 using a buffer solution, wherein optionally a filtration step is carried out before adding the acid. |
