Determination of Plasma Antioxidant Power in Capillary Blood through the Innovative system PAT (Plasma Antioxidant Test)

Validation of a patented method to determine the antioxidant capacity of human saliva based on the reduction of iron: the SAT test

The defense against damaging attack at mouth level caused by reactive species, in particular reactive oxygen species (ROS), is guaranteed by saliva, the main constituent of the antioxidant barrier. The aim of the performed tests was to establish the precision, linearity, and accuracy of the new patented test, SAT, on saliva samples taken from healthy volunteers. The analysis also provided useful information on storage conditions of the sample at low temperatures and on the normality range and defined the influences of interferences (in particular phosphates) in the determination

Performance evaluation of the innovative PAT test, comparison with the common BAP test and influence of interferences on the evaluation of the plasma antioxidant capacity

Antioxidants (AOs) represent the main barrier of defense against damaging aggression due to reactive species, in particular by reactive oxygen species (ROS). The plasma AO capacity is a measure of physiological, environmental, and nutritional factors (exposure to ROS and antioxidant supplementation) determining the redox status in humans and can underline the oxidative stress (OS) conditions in the progression/development of many diseases. Moreover, changes in AO plasma content after supplementation may provide information on the absorption and bioavailability of nutritional compounds and efficacy of AO therapy
