fibrinogen血液中的纤维蛋白原水平。
globulin the globulin level in the blood.
globulin血液中的球蛋白水平。
ESR the erythrocyte sedimentation rate, either less or
ESR红单元沉降率,无论是小于或
Details
详细信息----------Details----------
The erythrocyte sedimentation rate (ESR) is the rate at which red blood cells (erythrocytes) settle out of suspension in blood plasma, when measured under standard conditions. If the ESR increases when the level of certain proteins in the blood plasma rise in association with conditions such as rheumatic diseases, chronic infections and malignant diseases, its determination might be useful in screening blood samples taken form people suspected to being suffering from one of the conditions mentioned. The absolute value of the ESR is not of great importance rather it is whether it is less than 20mm/hr since lower values indicate a healthy individual.
红单元沉降率(ESR)是在其中的红血单元(红单元)沉淀出来的悬浮在血浆中,在标准条件下测量时的速率。如果的ESR的增加时,血浆中引起相关联的条件,如风湿性疾病,慢性感染和恶性疾病的某些蛋白质的水平,其确定可能会对有用的筛选采取血液样本的形式从一个人怀疑是痛苦所述条件。的ESR的绝对值不是非常重要的,而它是它是否是小于20mm/hr因为较低的值表示一个健康个体。
The question of interest is whether there is any association between the probability of an ESR reading greater than 20mm/hr and the levels of the two plasma proteins. If there is not then the determination of ESR would not be useful for diagnostic purposes.
感兴趣的问题是,是否有任何关联之间的概率ESR读数大于20mm/hr和血浆蛋白的水平。如果不存在,则ESR的测定不会是有用的用于诊断目的。
