Some experts suggest a longer duration of restricted activity of five to six weeks35 or even six months,36 although data from natural history studies do not necessarily support these recommendations. What is the difference between atypical and reactive lymphocytes? Reactive, or atypical, lymphocytes are relatively fragile cells, and as a result can be squeezed out of shape by surrounding cells, giving them a scalloped appearance instead of a smooth cytoplasmic edge.
