Correlation analysis on blood lipid of capillary and vein of the elerly in a community

Objective To study the difference and correlation of blood lipid of capillary and vein of the elderly in a community,and explore the reliability of the determination of blood lipid in capillary. Methods A total of 408 cases of blood lipid from capillary were measured by CardioChekTM and blood lipid from vein by automatic biochemical measurement at the same time. Results TC from capillary vessel was higher than that from vein(t=10.13,P<0.001),TG from capillary vessel was lower than that from vein(t=11.96,P<0.001).TC and TG in capillary vessel had positive and close correlation with biochemical analyzer(r² 0.625 and 0.705 respectively).Conclusion CardioChek^TM is quick,simple and easy to accept by older people for blood lipid measurement, and measurement of blood lipid from vein could be replaced by that of blood lipid from capillary vessel.
