For example, add another 120 samples and found that the concentrations of blood have a value higher than the value of the concentrations detected in the blood of the first summer.
Thus adding another 120 samples and found that the concentration of the blood is higher than the concentration of blood detected in the first of the summer.
Add more examples 120 samples. It was found that the concentration of blood is higher than the concentration of blood was detected for the first time in the summer.
