[0074] A preparation method of a skin allergen patch test diagnostic matrix composition, comprising the steps of:
[0075] 1) Preparation of body temperature liquefaction combination matrix: First, put the body temperature liquefaction combination matrix accounting for 80-90% of the composition mass percentage in a 60-80°C constant temperature water bath to dissolve, mix well, and then set the temperature of the constant temperature water bath is 45°C. The body temperature liquefaction combination matrix is composed of polyethylene glycol (PEG) and / or propylene glycol, wherein polyethylene glycol (PEG) includes polyethylene glycol 300 (PEG300), polyethylene glycol 400 (PEG400), polyethylene glycol Glycol 600 (PEG600), polyethylene glycol 1000 (PEG1000), polyethylene glycol 1450 (PEG1450), polyethylene glycol 1500 (PEG1500), polyethylene glycol 2000 (PEG2000), polyethylene glycol 3305 (PEG3305) ), polyethylene glycol 4000 (PEG4000), polyethylene glycol 6000 (PEG6000).
