The Lactate test strip is made up of four layers as follow
The Lactate Determination Process:
A drop of fresh capillary blood is placed on the top yellow mesh layer of the test strip. This passes through to the second layer where the red blood cells are separated with the blood plasma passing through to the third layer. Within this layer a chemical reaction occurs in the detector film resulting in a colour change which is observed by the reflectance photmeter. This reaction takes approximately 60 seconds.
