翻译一段四代联酶试剂4周后能否测得p24. 来自 medhelp
本帖最后由 nlzhr 于 2011-4-5 16:56 编辑There is lots of comment about the supposed sudden disappearance of p24 antigen at 28 days. This does not happen and the p24 element will remain elevated for at least 8 to 10 weeks and if you look hard enough it is present through the remainder of the illness.
P24 is a by-product of viral replication. As viral replication increases with initial infection then p24 is produced in huge amounts. As viral replication slows as your body hopefully attempts to regain control p24 will drop. However, the majority of people infected with HIV will develop antibdoies detectable by third generation tests at 4 weeks and over 99% by 6 weeks. 1st and 2nd generation HIV tests - still in use in certain parts of the world (including parts of the US until 2005) were poor, gave variable results and were unreliable.
有不少文献讲述 在28天以后，P24抗原会突然消失。这种情况是不会发生的，P24抗原会持续升到至少8到10周。
P24是病毒复制的副产品，当病毒复制量增加时，p24的量会激增，当病毒复制减少时，也就是你身体产生大量抗体时，p24会减少。然而，大多数人感染hiv时，三代试剂会在四周内检测到抗体，超过99%的人会在六周检测到抗体。1代，2代则做不到这点，会给出不同的不可靠结果。
结论：四代试剂比三代六周提前2周检测到HIV感染的抗原和抗体。
正确。 呵呵。我就是学习英语呢，好几年没看了。正好练习下。
我也小恐一名呢。 不错的帖子，楼主以后多翻点这样的给大家看看吧，可以当做心灵鸡汤~ 也就是说四代酶联四周可以排除99%了？
