collapse
reference range
comparison become a range of values with high and low limits
Blood loss to a point where life cannot be sustained is called:
exsanguination
lipid
fat soluble
diurnal/ circadian
happening daily; having 24 hour cycle
sclerosed
hardened
an arm that is paralyzed

postural pseudoanemia
posture related false anemia
jaundice ( icteric)
relating to or marked by jaundice and is used to describe serum, plasma or urine specimens that have abnormal deep yellow to yellow- brown color due to high bilirubin levels
