title: [Blood routine tests in capillary blood compared to those of venous blood].
abstract: When the venipuncture is difficult, should the blood routine tests be performed on capillary blood? Are there any differences in blood routine tests between capillary blood and venous blood? Many studies have been made of infants before our study, but there are few studies of adults. For the purposes of this study, we compared blood routine tests in capillary blood with those of venous blood in adults. Capillary blood and venous blood were drawn at the same time from 50 adults to estimate the values of blood routine tests. Specifically, blood specimens were drawn to estimate RBC, WBC, Hb, Hct, MCV, MCH and MCHC values by coulter counter model S7, while platelet value was estimated by ULTRA FLO 100. The results are presented follows: (1) The differences are non-significant in RBC, WBC, Hb and MCH between the venous blood [453.74 +/- 85.4) x 10(4)/cmm, 8290 +/- 4074/cmm 13.53 +/- 2.42 (gm%), 30.23 +/- 2.55 (pg] and the capillary blood [463.14 +/- 94.57) x 10(4)/cm 8182 +/- 4268/cm, 13.82 +/- 2.61 (gm%), 30.12 +/- 2.21 (pg]. p greater than 0.05. (2) The values of the Hct and MCV in capillary blood (44.02 +/- 7.78 (%), 95.34 +/- 7.33 (fl] are significantly higher than those of venous blood (40.64 +/- 6.83 (%), 89.94 +/- 6.94 (fl]. p less than 0.05. (3) The values of the platelet and MCHC in venous blood (29.29 +/- 10.5) x 10(4)/cmm, 33.17 +/- 1.09 (%] are significantly higher than those of capillary blood (18.44 +/- 8.1) x 10(4)/cmm, 31.38 +/- 1.01 (%]. p less than 0.05.(ABSTRACT TRUNCATED AT 250 WORDS)
