Abstract
Whole blood is an inhomogeneous, thermally fragile liquid suspension. It was shown that photothermal radiometry yields meaningful results, but required irradiation level might disturb the sedimentation process. Despite the necessity for direct contact, photopyroelectric method is more sensitive and also easier and cheaper to implement for routine measurements. All the experimental results are in a good agreement with developed theoretical models.
