Nuclear Medicine In
vitro testing involves the reaction of a sample (blood, urine, etc.) collected
from the human body with a reagent containing an isotope (I-125) in the test
tube detecting various hormones, serum proteins, tumor markers, It is a very
useful and accurate test method to observe the presence and course of the
disease by measuring the tiny concentration of trace substances such as
antibodies and drugs.
and IRMA (immunoradiometric assay) studies are performed to measure very small
amounts of biological materials such as hormones and tumor markers. In
addition, some important functional parameters of the body such as GFR
(glomerular filtration rate) can be measured in the laboratory.
• Thyroid hormone
(T3, T4, TSH, Tg, Tg-Ab, etc.)
• Sex hormone (LH,
• Viral markers
(HBV, HCV, etc.)
• Tumor markers
(AFP, CEA, PSA, etc.)
beginning of In-vitro Examination.
In 1971, the
introduction of the scintillation gamma counter began to be used in clinical
medicine. Endocrinologic studies have been actively conducted measuring all
hormones by radioimmunoassay, and measuring the concentration of various tumor
markers, hepatitis antigens, antibodies, and vitamins studies have been
expanded to oncology.
The test equipment
started with gamma ray and beta ray, but the automatic dispensing system was
introduced for the first time and automation of the work was started.
Trends of In-vitro Examination
In recent years, we
have an implementation of nuclear medicine automation system by domestic
technology, developing the latest equipment such as electronic fairing
equipment, gamma ray measuring instrument, and automatic washing machine, and a
good radiation immunity measuring kit is being developed. In addition,
according to the increase in the number of examinations and clinical demands,
the service is improved so that the one day medical treatment can be performed.
The rapid test report system such as tumor marker, thyroid hormone and
hepatitis tests. And received the ‘ISO 15189 internationally accredited medical testing institution
accreditation administered by the National Institute of Standards and
Technology. ISO 15189 is the only international standard to ensure that the
tests performed at medical testing laboratories are technically competent and
