Along with the CT technological development, especially
development of the positronic CT, the demand for using positronic
radioactive isotopes is called for, such as C-11, N-13, 0-15 and
These isotopes are all the basic components of human body

therefore, they can more faithfully reflect the intravital status

A Drop of Blood Shows the Whole Body External RIA
Radioimmunoassay (RIA) is an ultramicro method of analysis
capable of analyzing the extremely tiny amount of bio-active
substance in the blood, such as hormonic drug, protein, tumor-
correlative antigen, CGMP, DNA ...
thus able to determine the
physiological and pathological states of the human body. This
technology has been widely applied in pharmacology, materia
`medica, biology, oncology, bio-chemistry, hematology, gynaecology
and
and obstetrics / forensic medicine.
By now, it has become a con-
ventional-analysis means with over 300 detectable bio-active
matters. In the market are available the whole sets of RIA
kits, which are recommended for the easy operation and application,
especially suitable for diagnosing on pregnant women and children.
