* † Greenson ''et al.'' says ''>2 lymphocytes/HPF, where 5 HPF are sampled with the 40x objective''. Since the sample area given by Greenson ''et al.'' is 0.94 mm<sup>2</sup>, the field diameter is ~ 0.4892 mm. This field diameter corresponds to a 20 mm eye piece (0.4892 mm * 40x = 19.57 mm).

**Many microscopes in use today have a field diameter (at 40x) of ~ 0.55 mm; thus, 4 fields would be approximately 0.95 mm<sup>2</sup>.
