Can a lab urine pregnancy test be wrong?

The lab urine tests looks for the presence of HCG (a pregnancy hormone) in your urine.

if you get a positive- the only way it's wrong is if you've taken HCG containing medications (for infertility treatments) or if you have a tumor that is producing HCG-very rare.

if you get a negative- the test could be wrong if it was done too early after ovulation, you could be pregnant, but not producing enough HCG to show up in a test.

How long do benzos stay in your system if you take them everyday?

I was a chronic Benzo user and am now recovering. I spent six weeks in a rehab center, and didn't test clean for Benzos until day 41. They stay in your system a very very long time if you are a regular user.

Is Fentanyl tested on a UA?

I was wondering the samething...so after experimenting and obtaining three single panel tests for different opiates; I've concluded that having fent in the system will not show up on an "opi" (tests for: heroine, morphine, codeine opium), nor will it show up on an "oxy" test, and it will not show up on a methadone "mtd" test. On a standard U/A, opi is standard, methadone is sometimes on it--and oxy may be too. Fentanyl is a special opiate, b/c it's synthetic and hard to test for....test yourself first! hope this was helpful.

What is the normal range of tacrolimus level?

I had a kidney/pancreas transplant 9 months ago. My last tacr level was 10.7, which my coordinator called "toxic." - way too high. It should be below 9. at 9 months post-op, he said it should be around 6-8. Sorry, I don't know what the Low-Normal number is, but it's probably not much below 6.

Normal range=5 to 16,it must be below 14 after 3 month post transplant.

Why do stage 2 dengue fever victims need to take blood pressure?

I'm going to have to make a few assumptions here: * I assume you're discussing the Dengue Hemorrhagic Fever (DHF) and not just Dengue Fever (which manifests without the haemorrhagic features). * I further assume you're identifying "stage 2" as the point in DHF, after about 10 days, when hemorrhagic symptoms manifest. If that's the case, hypovolemia is one of the more dangerous effects and presumably could be diagnosed by a lowered BP, at which point you'd consider transfusing serum or perhaps whole blood, as conditions allow. Fluid replacement is key to the patient's survival in this phase. More, while DHS has no direct antagonist, palliative measures are very effective, with CDC saying that untreated DHS has an M&M of nearly 85%, while with treatment, this drops to 1%. DHS is managed by vector control.

Will you pass an Etg alcohol test after 60 hours. I am 160 pounds and saunaed it hard?

It's possible. It depends how much of the chemical was in your system originally.

Sauna has little or nothing to do with it, btw. In fact, becoming dehydrated could concentrate the chemical. We'd just try to remain abstinent instead of trying to beat the ETG test. It is, if anything, too sensitive, and beating it is pretty difficult, although 60 hours might do it.

How do atrial natriuretic peptide and brain natriuretic peptide reduce blood volume'?

ANP and BNP act when myocites are stretched in the heart as a result of fluid volume overload. Although many states could cause this it is most often attributed to ventticular dysfunction in the setting of hear failure. Both ANP and BNP act on tissues throughout the body to promote diuresis (after load reduction) and vascular muscle dilation (preload reduction). ANP and BNP are known to inhibit sensatio of thirst and drinking as well as inhibit the Renin-Aldosterone system causing diuresis (increased urination of fluid) as well as reduction of sodium. Increased endothelial permeability of vasculature allows more diffusion of salts and water out of the blood stream and into the renal vasculature. Hope this helps a little.
