A STUDY OF THE UTILITY OF BLOOD THEOPHYLLINE MEASUREMENT KIT ED009 USING BIOTRACK 516

In this study blood levels of theophylline were measured by using simple apparatus, Biotrack, Vision, and TDX. Studies were carried out on 55 patients with bronchial asthma (41 malesand 14 females with a mean age of 8.5±3.6 years) who were attending the Department of Allergy of National Children' s Hospital, performing a total of 99 sessions of blood theophylline mesurement. Blood was sampled when the patients visited the outpatient clinic, and blood levels of theophylline were measured by using three kinds of apparatus, Biotrack, Vision, and TDX. The masurements obtained by the three methods were analyzed for correlation between the three apparatus so as to determine the clinical utility of Biotrack. There was a significant correlation (r=0.978) between Biotrack and Vision (p<0.01), and there was again a significant correlation between Biotrack and TDX (r=0.977) (p<0.01). Based on the results presented it may be concluded that Biotrack favorably compares with other conventional apparatus for mesurement of theophylline in the blood. Furthermore, considering the fast results and high procedural simplicity, Biotrack seems to be a blood theophylline measurement apparatus of clinical use.
