An assessment of Stat Tek: a reagent-strip method for glucose determination.

Stat Tek, a reagent--strip method for glucose determination, has been evaluated. Aqueous solution of glucose standard is not recommended. The linearity of serum glucose is between 630 to 3,450 mg/l. The within run precision is between 0.7% to 3.0%. The day-to-day precision is between 2.8% to 5.6%. The recovery of glucose added to serum is between 95 to 101%. The correlation of glucose by Stat-Tek and SMA 6/60 show small proportional and constant errors. Stat-Tek is simple and easy to use; however, proper quality control and training of the user are essential for the correct measurement of glucose.
