glucose oxidase procedure |
|
Definition
you have to have at least 5 test tubes (blk, L1, L2, Std, and Patient) filled with glucose liquicolor reagent. Then add correct ingredients to the labeled test tube and mix and incubate. Record the absorbances at 500nm then calculate the concentrations of the controls and the patients using beers law. |

Term
The principle of the glucose oxidase procedure |
|
Definition
glucose oxidase enzyme will convert glucose in to a product, which can be used in another reaction to produce a colored complex. The colored complex can be measure spectrophotometrically and the absorbance is proportional to the amount of glucose in the sample. |
