Abstract An in vitro testing method for the diagnosis of malignant tumours, preferably human tumours, comprising determining the mobility variation of cellular blood components contacted with a migration inhibition factor (MIF), wherein the MIF is secreted from lymphocytes being sensisized against tumour tissue, whereby subjecting, as said cellular blood components, the lymphocytes as a part of a leucocyte suspension to be examined prior to a migration inhibition test. The lymphocytes are contacted with an antigen capable of stimulating them to produce MIF. The leucocyte migration is inhibited and fixed after a predetermined period of time. The leucocytes migrate in a capillary intermediate layer having a thickness of from 1 to 20 microns and being at least partially filled with liquid. Said intermediate layer is formed between a glass surface and an agar layer. The invention further refers to the construction and preparation of a testing plate or dish.
