Clinical comparison of different blood collection methods in routine blood test results

Objective To compare clinical value of peripheral blood collection and venous blood collection methods in blood tests. Methods 467 patients who received blood test were selected.The venous blood and peripheral blood were collected, the indicators of blood test were detected, and the test results were analyzed. Results The white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), red blood cell hematocrit (HCT), hemoglobin (HB) of venous blood were (5.7±1.2)×109/L, (3.72±0.48)×109/L, (218.0±57.5)×109/L, (41.8±19.8)g/L, (115.7±13.8)g/L respectively, those of peripheral blood were (6.7±3.4)×109/L, (3.62±0.72)×109/L, (204.0±87.7)×109/L, (32.7±20.7)g/L, (103.6±19.6), the differences were statistically significant (t=5.994, 2.497, 2.885, 6.865, 10.908, all P 0.05). Conclusion The test results in patients with venous and peripheral blood was quite different, venous blood test results obtained with greater value in clinical use, it is recommended that routine blood test used venous blood.
