The healthcare professional will not advise smoking before taking the test as it is done on an empty stomach. And smoking cigarettes on an empty stomach can skew the results. In a smoker, the level of catecholamine in the blood increases, as well as carboxyhemoglobin and cortisol. This is followed by: the indicator in eosinophils - lower and higher in neutrophils. A bad habit provokes other jumps in indicators, therefore, judging by the blood from a finger is hardly possible.
