A method to provide control samples for validating a diagnostic test within a laboratory system is presented. The laboratory system comprises an aliquoting device, a storage, a transport system, at least two analyzers, and a control unit. A total number of control sample aliquots and an aliquot volume for each control sample aliquot is determined based on a validation time schedule. A provided total control sample volume is aliquoted into the determined total number of control sample aliquots with the determined aliquot volumes. The generated control sample aliquots are transported to one or more of the at least two analyzers according to the validation time schedule.

The present invention relates to a transfer platform for a biological sample analyzer, comprising a movable carrier plate and an object stage which is placed on the carrier plate and separable from the carrier plate. The side of the carrier plate facing the object stage is an upper surface, and the reverse side is a lower surface. The side of the object stage facing the carrier plate is a lower surface, and the reverse side is an upper surface. The object stage and the carrier plate are respectively provided with magnetic blocks that magnetically attract each other. When the object stage is placed in a predetermined area on the carrier plate, the suction of the magnetic blocks automatically positions the object stage relative to the carrier plate, thereby achieving the technical effect of blind positioning. The present invention can be applied to test analyzers for specific proteins, cholesterol, heme, routine urine test, dry biochemical test, etc. The present invention has the advantages of convenient operation, time and effort saving, high efficiency and the like. Meanwhile, the present invention is simple in structure and low in cost, and is suitable for wide promotion.
