The system comprises a straw and a liquid dilution medium. The straw comprises a tube (11) extending between a first end and a second end and comprises a gas-permeable, liquid-tight plug, said plug being arranged in the tube (11) in the vicinity of the first end of same and extending between a first end turned towards the first end of the tube (11) and a second end turned towards the second end of the tube (11). Said plug comprises an element (14) impregnated with a reagent (22) at least in the vicinity of a first end turned towards the second end of the tube (11). The liquid medium is provided to produce, by mixing, in predefined conditions, the liquid substance (21). The reagent (22) and the medium(27) are configured such that, when the substance (21) comes into contact with the first end of the impregnated element (14), it forms a hydrogel.

A test pad comprising multiple test patches and urine detection patches in an array is described. The test pad is suitable for automated urine analysis of multiple animals in a cage. Urine detection patches may be arranged in a BAYER pattern or as rings. Multiple layers, including a substrate, a wicking layer, a test patch layer, and optional protection layer serve to manage puddles of urine. Various isolation elements are described that keep urine puddles from spreading. Color reference spots on the pad are used for dynamic color determination of test patches. Urine detection patches start a read clock and identify which test patches are valid. Elements to hold and align the test pad are described. Methods of detection and reading are described.

A method of in vitro fertilization wherein the embryo is implanted into the uterus of a female patient at least two, and preferably three to twelve months after the eggs are retrieved from the patient in order to reduce the effect of autoimmune rejection of the embryo by the patient's autoimmune system and increase the probability and success of pregnancy and wherein prior to embryo implantation, the endometrium in the uterus is prepared for embryo implantation by introducing peripheral blood mononuclear cells (PBMCs) into the uterus. The procedure is combined with cryopreservation techniques to preserve the oocytes or the IVF-produced embryos of the patient.
