A laboratory system is disclosed. The laboratory system comprises a plurality of laboratories comprising one or more analytical instruments for performing a plurality of analytical tests (T1-n) and providing analytical test results (TR1-n) and a remote computer communicatively connected to the laboratories. Each of the laboratories is configured to define test result validation criteria (C1-n) for validating at least one of the analytical test results (TR1-n) associated with the respective analytical tests (T1-n) of one of the plurality of laboratories. The remote computer is configured to define a plurality of profiles (P1-n) of validation criteria, to assign the profiles (P1-n) of test result validation criteria (C1-n) to one or more of the laboratories (102), and to perform an automatic validation of groups (G1-n) of the analytical test results (TR1-n) according to the profiles (P1-n) of test result validation criteria (C1-n).
