看了一下 貌似确定感染的人CD4细胞的比例在20%以下
The absolute CD4 cell count bounces around significantly, as it is influenced by a number of factors, including time of day, stress/fatigue levels, non-HIV concurrent infections, etc. Infections have the largest impact on CD4 cell counts. Whenever your body fights any infection, the number of white blood cells goes up and consequently the number of CD4 cells rises as well. Vaccinations can also cause this same effect. That's why it's best not to check your CD4 cell count until you've completely recovered from an infection.
Absolute CD4 cell counts are reported per cubic milliliter of blood. (The normal range varies somewhat from lab to lab, but is usually around 500 to 1,600. Because CD4 counts are so variable, we often prefer to monitor CD4 percentage, the percentage of total lymphocytes comprised by CD4 cells. For example, if your CD4% is 20%, one out of five lymphocytes is a CD4 cell. This percentage is more stable than the absolute number of CD4 cells, as it is less affected by the factors mentioned above. The normal range is usually 20% to 40%. A CD4% below 14% indicates severe immune deficiency and is a criterion for the AIDS diagnosis, as is an absolute CD4 count below 200.
这里解释一下划线部分：一般来说正常的CD4细胞比例在总T细胞数量的20%-40% 如果这个比例低于14%说明免疫系统出了问题 而这个对于AIDS诊断来时相当的重要 同等的说 和CD4细胞绝对值小于200是一样的。
大概这个意思 这里没有提CD/CD8的比值 而说的是CD4和全部淋巴细胞的比例~ |
