刚收到一封信,有关 my baby's newborn screening blood test results.
上面说:
Your baby has a variant hemoglobin trait.
this means that each red blood cell contains both normal hemoglobin and an
unusual hemoglobin.
大家有收到过这样的信么?是很严重的问题么?该怎么办?

Hemoglobin A1c measures glycosylation on the hemoglobin protein due to
high glucose concentration in the blood. Since normal red blood cell has
a life span of 120 days, Hemoglobin A1c provides an averaged estimate of
blood glucose concentration in 3 months, in comparison to direct glucose
measurement, which is always a snapshot and can be influenced by multiple
factors. It is beginning to be used in Chinese hospitals and you just
need to ask for it. In a healthy individual, A1c should be <7.0

Serum test theta has a reference interval from 0 to 5 mg/dL. Changing the
reference interval to 0 to 10 mg/dL would do which of the following?
A. Increase the specificity
B. Increase the sensitivity
C. Increase the number of false-negative results
D. Decrease the number of false-positive results
E. Not alter the sensitivity or specificity
正确是B。
我的理解是,如果reference interval被扩大了,说明会有更多的超出本来的正常范围
的数值被当做正常,比如8,原来是超出范围的,现在会被认为是在reference

From Wikipedia, the free encyclopedia
Bohr effect is a property of hemoglobin first described in 1904 by the
Danish physiologist Christian Bohr (father of physicist Niels Bohr), which
states that an increasing concentration of protons and/or carbon dioxide
will reduce the oxygen affinity of hemoglobin. Increasing blood carbon

好的答案,唯一的建议是跟医院保持好的沟通,有礼有节(其实没有人希望这样的事情

大增加,心脏泵血能力也强大。血色素是血红蛋白的测量指标。 血红蛋白hemoglobin
是血液携带氧气的载体。 在高原训练可以增加血液的携氧能力。 肯尼亚的长跑运动员
就是长期在高原训练,其持久力惊人。
拉萨是一个现代化城市,生活方便,交通方便,很适合居住。 运动员在那里不会感到
