1. LFT (Liver Function Test), ammonia, amylase, lipase :간기능검사
⑴ 정의 : 간기능의 상태를 조사하기 위한 혈청 내 효소치를 측정하는 검사 방법
⑵ 용도 : 지표가 되는 효소 및 단백질 등이 혈액 중에 얼마만큼 함유되어 있는가를 측정하여 간 접적으로 파악, 간 손상의 정도와 존재 여부, 간질환의 경과
blood chemistry)
● 목적 : 혈액 속의 여러 성분을 생화학적 방법으로 측정하는 것으로 혈청단백질(알부민과 글로블린), 전해질(나트륨 ·칼륨 ·염소 ·칼슘 ·인 등), 혈당 ·요소 ·질소 ·각종 지질(콜레스테롤 ·인지질·중성지방 ·유리지방산 등), 혈청효소활성(트랜스아미나아제 ·알칼리포스파타아제 등)

TWO BOYS, JEFF AND KENNY (14), trailer park, punks come
running out of the woods, rocks in hand.
Rudy and Jacob climb the tree, using makeshift RUNGS that are
nailed into the trunk. In the floor of the tree house is a
DOOR. Rudy removes a KEY from a chain around his neck and
unlocks it. He climbs inside and pulls Jacob in after
Bloody crimes were being committed

It wasnt going to be
an ordinary war, he said...
... but rather a war in which no side
was entirely innocent.
Its like a humans insides.
Entrails and vitals.
See, thats his digestive system.
Circulatory system.
Respiration. Lungs.
Fatty tissue. Kidneys.
The ammonia?
Thats his plasma.
Got it?
But, Dad...

Bacillus bacteria causes fermentation by breeding
⇛ Composition of soybeans becomes changed by
Bacillus subtilis(natto), Bacillus licheniformis,
Bacillus megaterium
Changing of ingredient - PH
By Bacillus subtilis protein may lead to ammonia burn.
→ Ammonia is produced.
→ PH is increased.
5)검체처리
CK, LD, phosphate, ammonia 등 분리하지 않고 방치하면 검사치가 증가하고, Glucose, bicarbonate, acid phosphatase 등은 감소한다.
일반적으로 항응고처리된 혈장은 1시간 내에 세포 성분과 분리되어야 하고 혈청은 2시간 내에 분리도어야 한다. 대개 검체가 응고되는데 20~30분이 필요하다.
