To answer your  question on CD4 i ve pasted this excerpt. Please note the normal ranges.

CD4 cells are a type of white blood cell
that fights infection. Another name for
them is T-helper cells. CD4 cells are
made in the spleen, lymph nodes, and
thymus gland, which are part of the
lymph or infection-fighting system. CD4
cells move throughout your body, helping
to identify and destroy germs such as
bacteria and viruses. 

The CD4 count measures the number of CD4
cells in a sample of your blood drawn by
a needle from a vein in your arm. Along
with other tests, the CD4 count helps
tell how strong your immune system is,
indicates the stage of your  HIV
disease, guides treatment, and predicts
how your disease may progress. Keeping
your CD4 count high can reduce
complications of HIV disease and extend
your life.       

33 Million People Now Live With HIV. How
Did We Get Here?             How HIV
Affects CD4 Cells 

HIV targets CD4 cells by: 

   
-  Binding to the surface of CD4 cells 
-  Entering CD4 cells and becoming a
  part of them. As CD4 cells multiply to
  fight infection, they also make more
  copies of HIV 
-  Continuing to replicate, leading to a
  gradual decline of CD4 cells 



HIV can destroy entire "families" of CD4
cells. Then the diseases these
"families" were designed to fight can
easily take over. That's when
opportunistic infections are likely to
develop.   When to Have a CD4 Count Test


Your doctor will recommend a CD4 count
test: 

   
-  When you're first diagnosed with HIV.
  This is called a baseline measurement.
  It allows you to compare against
  future measurements. 
-  About two to eight weeks after
  starting or changing treatment. 
-  Every three to six months after that
  (is a reasonable time interval). 

What the CD4 Count Test Results Mean 

CD4 counts are reported as the number of
cells in a cubic millimeter of blood. A
normal CD4 count is from 500 to 1,500
cells per cubic millimeter of blood. It
is more important to pay attention to
the pattern of results than to any one
test result. 

In general, HIV disease is progressing
if the CD4 count is going down. This
means the immune system is getting
weaker and you are more likely to get
sick. In some people, CD4 counts can
drop dramatically, even going down to
zero. 

The test does not always correspond with
how well you are feeling. For example,
some people can have high CD4 counts and
do poorly. Others can have low CD4
counts and have few complications. 

If your CD4 count goes down over several
months, your doctor may recommend: 

   
-  Beginning or changing antiretroviral
  therapy. 
-  Starting preventive treatment for
  opportunistic infections. 



Public health guidelines recommend
starting on preventive antiretroviral
therapy if CD4 counts are under 200,
whether or not you have symptoms. This
is a later stage of HIV infection called
AIDS (acquired immunodeficiency
syndrome). Some doctors start therapy
earlier, when the CD4 count reaches 350.
If therapy is effective, your CD4 count
should go up or become stable. 

Most doctors recommend starting
medication  for opportunistic infections
at these levels[/b]

Hello MCLOVIN
Im in a bit of a fix. I know you frequent this forum, so please read this.
I have a close friend with full-blown AIDS ive been trying to manage for close to 2yrs now.
He is 60years old, he cannot tell how or where he contacted it.
His meds are zidovudine which no longer seem to maintain him. His last CD4 was 145/mm3.
His main problems 2 weeks ago were weakness drowsiness and vertigo.
He had a lumbar puncture done which was clear and revealed normal glucose levels and protein of 0.7g/L ,so we're thinking of (query) a viral encephalitis.
We adminisitered aciclovir 900mg 5times a day for 5days after which he improved . A lumbar puncture done 2 days ago tend towards normal parameters. He now alert and eating well. A liver function test showed all enzymes grossly elevated, he's however not icteric or febrile his stools are of normal pigmentation. I dont believe he has a viral hepatitis, so could it be his meds causing this ?
Anyway, Im now looking into alternative measures to manage him. I dont believe he's a candidate for colloidal silver in view of his derranged liver function.
I read a blog written by you on a facebook group(with your real name and mobile no.) describing a regime of IM or oral sodium ascorbate and some amino acid supplements as an effective method of decreasing viral load and boosting T-helper cell clusters. I guess it works, cause I read some entries by one or two whose viral loads are now undetectable using it.
Im NOT trying to cure my friend, if I can extend his life another few years .i'll be satisfied . I need to know the exact doses and intervals, ive been calling your number but its always busy.
Pls call me on 01-774086 or send correspondence to me via ohiye@hotmail.com
Renumeration for any solution or service you can provide is no object.
Thank you as you respond.
