Digital commercial swamedication is a device that can use to check the health profile of the user with a few blood sample to gain health information. Nowadays, it has been many devices for cholesterol blood measurement are marketed. The research goal is to determine the validity and reliability of three brands of the digital commercial device and to observe the impact of sampling location to the value of the result. Validity test was done by measuring the blood sample from capillary and peripheral using the devices and comparing the result towards the spectrophotometry-enzymatic method. Data obtained was then processed statistically using IBM SPSS with T-test pair. Reliability test was performed with measuring cholesterol blood level by the digital commercial device on subjects for seven days. It was conducted on the right hand and left hand, with the position of blood sampling on the thumb and middle finger for each hand. Data obtained was then processed statistically using IBM ????­?®??? ?ð?ã ?í± » ®???? ??± ?» ???????­ ®í?? ??í ?í± ¸ ? ?±?± ???®±??±¸ ?? ?ð??ð® ?????ð?ã IBM SPSS with T-test pair, too. The result showed that the highest validity belonged to A, with probability value 0.801 (not significantly different toward the laboratory instrument). Meanwhile, the lowest valid device was brand B, with a probability value of 0.019 (significantly different). The highest reliability of device belonged to C, with the mean value of Cronb ®í??!??í ??????????? ???? ®íð?ã ?? real, standard value 0.6). Meanwhile, the lowest reliability is in device B, with the mean value of ???????­ ®í?? ??í ????-0.0932 (the most unreliable). Reliability testing on each finger showed that the middle finger had ?í± íðãí±??? ??± ®??? ?±¸ ???í± ?í??­?í± íðãí±???± ??» ???????­ ®í?? ??í was owned by device C with the sampling location on the middle finger, with the value = 0.5682. Next, all device showed both samplings in the right hand, or left hand was not significantly different. Finally, the data set proved that most identic data was resulted by device A.
