The present invention relates to a method for detection of at least one target molecule in a blood sample comprising at least the following steps:(a) providing a blood sample; (b1) contacting said sample with an antioxidant and applying said sample to a filter to separate the blood cells from said sample; and/or (b2) applying said sample to a filter to separate the blood cells from said sample, wherein said filter comprises an antioxidant; (c) contacting said sample with a first binding molecule in the cartridge, wherein said first binding molecule is attached to a magnetic particle, and wherein said first binding molecule is capable of specifically binding to said at least one target molecule; (d) contacting said sample with a second binding molecule, wherein said second binding molecule is attached to a sensor surface, and wherein said second binding molecule is capable of specifically binding to said at least one target molecule; and (e) detecting the magnetic particles on the sensor surface. The present invention also relates to the use of an antioxidant in the process of detection of at least one target molecule in a blood sample as well as to cartridges for insertion into an assay device for detection of at least one target molecule in a blood sample. |
