From the urine test, a couple of weeks. The hair test will measure years, if your hair is that long.

What does CI means in blood work levels?

In various blood work panels, doctors check for levels of chloride (CI). Chloride is an electrolyte that comes from salt and can be measured in urine or in the blood.

There is also a sweat test that measures chloride levels to help doctors determine if a child is suffering from cystic fibrosis.

At what viral load and CD4 count level would ART be recommended?

This is quite a complicated question that depends on where you live and which treatments you can access.

Firstly, you need to be ready to start treatment, and understand the importance of adhering to treatment.

Secondly, it will depend on the guidelines in the country that you live.

Treatment guidelines from the WHO recommend starting when the CD4 count drops below 350. This is the case for the UK and many other countries.

The US guidelines recently raised this to starting at any count below 500, and some countries have followed this lead, while other think it is premature and is unsupported by sufficient clinical evidence.

If you have health complications (for example heart disease or hepatitis C coinfection), this may be a reason to start higher than 500.

Some of the panel members on the US guidelines wanted to recommend treating everyone at any CD4 count.

Finally, if you live in a country which only has access to drugs associated with complicated side effects like d4T (stavudine), then it may be better to wait until 200, as the risks from earlier treatment outweigh the potential benefit from startgin a little earlier.

What is Blood alcohol concentration 0f 2.2?

Standard alcohol measurements are given as a percentage content of your overall blood. A 2.2 blood alcohol concentration is not possible from drinking alcohol because death would come much quicker. I work in a detox and the highest I have ever seen was .561, which means just over half of one percent of overall blood content. This was a person with extremely high tolerance. Most people would be in danger at a much lower level. One college student in our town died from alcohol and the autopsy revealed .355. This doesn't mean .355 killed him. The body stops processing alcohol with death so he died somewhere on the way up to a .355.

Why does methadone show positive in urine drug screen when only percocet is taken?

Most likely you have the wrong drug listed as what is showing in the drug screen... I don't believe that methadone would show in a drug screen for percocet. Percocet is made of two active ingredients, Tylenol and oxycodone. oxycodone is derived from morphine, so it is possible that morphine may show in the drug test when percocet is taken.

How do you know if you are miscarrying if you test negative on a urine test but positive on a blood test but the hcg is only 7?

You can tell if you're miscarrying by the blood test. But it really depends on how long after intercourse you had the blood test performed. A HCG level of 7 is very low and may indicate a miscarriage. You need to have the blood test performed 48 hours after the original test.
