懂医学英语的请进，高分求这个体检单的翻译，只有几个单词，是国外的一个医疗机构出的，一定要专业准确
主要有以下几处:
Flag 该怎么理解，这一列下面怎么都是空白？
Units 应该是单位的意思吧，下面的qualitative如何理解？
HIV 1/2 Abs 应该是Ⅰ型及Ⅱ型艾滋病病毒绝对值数量，后面的p24 Ag(ECL)什么意思？
最后一行AGGL什么意思？
flag
n.旗；旗帜；信号旗
vt.(以旗子)标出
v.无力地下垂；减退；枯萎
qualitative
adj.性质上的；质的；定性的
后面的p24 Ag(ECL)什么意思？
P24 antigen
P24抗原
Formal name: p24 Antigen
What does the test result mean?
A positive result means that a person is likely infected with HIV. However, a positive screening test requires that a second test be performed to establish a diagnosis.
A negative result most likely means that a person is not infected with HIV or that the level of p24 is below the detectable limits of the test. If someone suspects that he has been exposed or if he is at an increased risk, repeat testing with a combination HIV antigen/antibody test is recommended.

I took another separate test for p24 Ag and they used the ECL technique.
ECL or autoradiography（n.自动射线照相术）?
ECL is an appealing technique because it is quick and very sensitive and does not expose the investigator to radioactivity. The use of radioiodinated protein A to detect bound antibodies is however usually a superior technique.

Western Blot Test
免疫印迹试验
Recognized HIV-1 viral antigens produce bands at gp160, gp120, p65, p55, p51, gp41, p40, p31, p24, and p18.
V.D.R.L. (Test Microflocc.Cardiolipinica)
Venereal Disease Research Laboratory test
性病研究试验室试验
（六）梅毒血清试验：近数十年来国外的免疫血清试验发展迅速，检测方法甚多，我国目前常用的有如下几种：
以抗原的不同分成两大类：
（1）非螺旋体为抗原（用心拟脂）以检测患者血清中是否存在抗心拟脂抗体，又称反应素。
a、性病研究试验室试验（Venereal Disease Reserch Laboratory简称VDRL）一以心拟脂作抗原，检测患者血清中反应素，有絮状物凝结，即为阳性。
AGGL可能是一个实验室的名字

The Venereal Disease Research Laboratory test or VDRL is a blood test forsyphilis and was developed by the former Venereal Disease Research Laboratory, now the Treponemal Pathogenesis and Immunology Branch, of the United States Public Health Service. The VDRL type test was invented before World War I, with its first iteration being that developed by August Paul von Wasserman with the aid ofAlbert Neisser in 1906.

Unit是单位，但是下面的qualitative是指这个测试的结果无需定量，话句话就说它只判断有还是没有，多少并不重要。
Reference Range就是正常指标的范围，如果数据落在这个范围内属于正常，但是由于所测项目属于定性测量，所以都是没有范围。
HIV1/2 ABS +p24 Ag这是指 艾滋病抗体加抗原的测试，括号里面的ECL代表测试方法，具体测试方法需要专业人士提供，这是一个比较复杂的内容。
VDRL这是梅毒的抗原测试， 详细请看http://www.bioon.com/Article/Class319/22387.shtml。括号内依然是测试方法，请不要太在意。
所有测试结果均为阴性，就是没问题。本回答被提问者采纳
