A diagnostic test and method is provided comprising mixing blood or another biological fluid sample with a test compound and spotting the blood on filter paper for subsequent analysis of the effect of the test compound on the blood. The biological fluid can be a cerebrospinal fluid, a peritoneal fluid, a cyst fluid, an amniotic fluid, a lavage fluid, a saliva, a cell extract or a tissue extract. The compound is chosen among an amino acid, a peptide, a protein, a carbohydrate, an oligosaccharide, a polysaccharide, a glycoprotein, a lipid, a lipoprotein, a glycosaminoglycan, a hormone, a steroid, a vitamin, a low molecular weight synthetic or natural compound which influences the blood to cause an alteration of its composition, e.g., a toxin, allergen, autoantigen, bacterial protein or polysaccharide, viral protein, fungal protein or polysaccharide, parasitic protein or polysaccharide, bacterial lipopolysaccharide or any other compound relevant to diseases.

Diagnostic blood test using adsorption on filter paper

A purification process for large-scale production of Gc-globulin is described. The source of Gc-globulin is preferably a crude plasma fraction but can be any solution, suspension or supernatant containing Gc-globulin, e.g., a milk product, colostrum or a fermentation broth. The Gc-globulin can be plasma-derived or produced by a genetic modified organism. The process includes two key elements: purification by series of ion exchange chromatography steps, and performing at least two virus-reduction steps. A diagnostic method to measure the free Gc-globulin in a patient blood sample, a use of Gc-globulin in medicine and the preparation of a Gc-globulin medicinal product is also provided. The product can be used in therapy for patients with circulatory disorders and complications, i.e., where it is contemplated that patients would benefit from the administration of Gc-globulin.
