[Basic biochemical blood parameters in astronauts in preflight training]

From the findings of biochemical blood analyses obtained during original examinations of 24 cosmonauts with a repeat blood sampling (2-5 times) of each test subject there calculated the mean values of norm and the interval limits of norm using 33 biochemical blood indices for a given group of test subjects. It is shown that in the absence of significant discrepancies from the generally used mean population standards for the cosmonauts it is typical of some specific differences from universally adopted standards of the parameters mainly related to energy metabolism.
