Morphological assessment of EOX in blood plasma is performed according to the test known as Optical Microscopy for cell analysis in vitro or HLB test, also known under the name Dry layer oxidative test, which the investigators refer to as microscopic morphology EOX in plasma (EEW). The EEW provides indirect information concerning EOX, among others, using the following grading system percentage of discontinuous area of the clot, present in the microscope slide: grade I (normal EOX rate, with total area of discontinuity of the extracellular matrix (ME) less than 10%), grade II (light EOX with ME discontinuity area between 10 to 20%), grade III (moderate EOX with ME discontinuity area between 20 to 30%), grade IV ( serious EOX with ME discontinuity area between 30 to 40%) and the grade V (very serious EOX with ME discontinuity area above 40%) 18. By lancing on the medial side of the digital pulp of the fourth finger of the left hand previously sanitized with alcohol, collecting the blood drop will be next to a microscope slide by five light touches this blade with the drop. After this procedure, the blade will be kept in place protected from contact with the blood and at room temperature (23 ° C) for the nine-minute period for the realization of the collected blood clotting process. At the end of this period, the morphological patterns of these clots are seen in an increase of 40 times as set out in protocolo18 and their assigned qualitative graduation will be logged into a spreadsheet for further statistical analysis.
