Figure 7: Blood interference in cell-block produced by Nano NextGen CelBloking™ kit from blood contaminated cytology specimens (same is applicable to any other method for blood rich specimens): (a and b) Section from the bottom portion of the wells with specimen sediments rich in red blood cells. The diagnostic tumor cells are missing in this zone, (c) the deeper levels showed more tumor cells, but this level cannot be predicted, and so the possibility of catching the diagnostic cells depends on chance factor with frequent sampling artifact
