The QuantiFERON-TB Gold blood test will come back with either a positive or a negative result. Results: Any. Specimen Requirements. The mechanism of action of a mitogen is that it triggers signal transduction pathways involving mitogen-activated protein kinase (MAPK), leading to mitosis. The "normal," "weak" and "negative" mitogen response (respectively) was associated with decreasing hemoglobin, albumin and lymphocyte counts, but increasing neutrophil count and C-reactive protein levels ( Table 1 ). Amitosis is a method of direct cell division in which the nucleus divides into two daughter nuclei without showing differentiation of chromosomes and development of spindle.
