Will second hand weed show on a hair test three weeks ago?

No, it won't, because only a trace will have settled in the hair, and will have been washed out. The hair test detects THC which has been deposited in the hair from the body, so it can be proven that a smoker has stopped taking cannibis, and how long ago that was.The test is not sensitive enough to detect the tiny amount you would have inhaled while you were in the car.

How dangerous is blood and protein in urine?

Proteins have no fiber and require adequate water to process. A diet too high in protein (over 60 gm a day on average) can overwork the kidneys. There are many supplements of wide ranging degree of quality on the market. Confer with a person experienced in the use of protein supplements before dramatically increasing your protein intake. Also consider the need for increased intake of fiber and water when supplementing.

What are normal liver function test results?

the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter.

Is a Fasting blood sugar of 116?

From your question I assume it is Fasting Plasma Glucose Test in mg/dl.

Normal Blood glucose level is 70 mg/dl to 99 mg/dl
Pre-diabetes Blood glucose level is 100 mg/dl to126 mg/dl

It means 116 mg/dl is pre-diabetes, that is you are not diagnosed as diabetes but you have more chances of getting diabetes.

So it is advisable to take every steps to avoid diabetes, particularly lifestyle changes is a most. Lifestyle changes by increasing physical activity, plan to reduce obesity or over weight, quit smoking and plan your food smartly.

What does NE and mo mean in your CBC blood?

How o blood group is formed?

Ali Al-Qhtani

The ABO antigens are terminal sugars found at the end of long sugar chains (oligosaccharides) that are attached to lipids on the red cell membrane. The expression of ABO antigens is controlled by 3 separate genetic loci:1)ABO gene located on chromosome 92)FUT1(H) gene on chromosome 193)FUT2(H) gene on chromosome 19( secretor gene)oThe expression of A or B antigens depend on H and Se genesAt least 2 genes, FUT1and FUT2oThe secretor population (80%), these antigens are found in soluble form in secretions and body fluids e.g. plasma, saliva.•They are responsible for production of H antigen •Both encode alpha 1,2 fucosyltransferase that catalyse transfer of fucoseto terminal galactose residue of the H precursor chain•FUT-1 is active in mesodermal derived tissues including hematopoietic tissues and is responsible for H expression on RBC•FUT2is responsible for the expression of H antigen on endodermaltissues including those responsible for secretion and hence the gene responsible for ABH secretion

Precursor chain of

sugars is formed most

frequently as either

Type 1 or Type 2

depending on the

linkage site between

the

N-acetylglucosamine

(G1cNAc) and

Galactose(Gal).

•Secretors are homozygous or heterozygous for the active allele (Se) ,non secretors are homozygous for the inactive allele (se).

-Type II found on RBC

Type I&II found in secretion

If one parent is B positive and the other one is O positive what blood type would the child have?

We are looking for the possible blood types of a baby.

Parental information:

  • Mother type B neg -- can be BB or BO and onlyRh (--)
  • Father type O pos -- can only be be OO and Rh (++) or (+-)
Baby recieves one gene from each parent:
  • Baby is type BO (+-) = B pos
  • Baby is type BO (--) = B neg
  • Baby is type OO (+-) = O pos
  • Baby is type OO (--) = O neg
Therefore the baby could be Type B pos/neg or Type O pos/neg.

Why is klonapin not showing up in your urine?

Klonapin would show up as a benzodiazepine for up to 7 days at a therapeutic level, 30 days for chronic users. Since the drug is typically precribed for the user it raises no flags on normal urine tests.

Ls there any known way to pass an ETG alcohol tes when you have been drinking?

ETG tests are highly flawed due to not being discriminative enough where the alcohol is comming from. People have lost their jobs, licenses, etc and didn't drink. Those in the healthcare field will fail automatically due to the need to constantly use Purell; over 700 ng, almost 800ng, and the limit is 100. Considering an alcoholic beverage will cause 6000 ng, having the positive results at 100ng is rediculous!

Lysol disinfectant alone will cause a false positive. Foods, including ripe fruits, will cause false positives. Not only these but also cleansers, toothpaste, mouthwash, breathfresheners, some aerosol products, food enhancers such as extracts, hairspray, deodorant, over the counter medicines, and the list goes on.

They say that only ingestion will cause a positive result but this was clinically found to be false ...inhaling the fumes will also cause a false positive result which was shown with the use of Purell. It may just have been a guess, by the scientists, that it was just the inhaling of the fumes, but your skin is the biggest organ in you body and I believe that absorption must be considered as well! I personally don't know how anyone can pass it. I would fail alone just from my coffee with Vanilla extract in it every morning. Or my whip cream on ice cream.

This test is completely unreliable.

Father is A negative blood and mother is O positive blood what type blood will the baby have?

I am O positive and my husband is A negative, and our son is A negative, for some reason children mostly take their fathers blood group, but not always, other possible blood groups the baby could be would be either yours or your husbands blood type.

Unless specifically ordered to get tested for will marijuana show up in a urine or blood test?

no, the test must be specific drug test to look for THC-and you must be told its a drug test. i used to work machining brass which required frequent blood tests for lead, the company were very anti-drug, myself and many others smoked pot regularly, no problems - they would have fired us on the spot if they knew - tee-hee

What is vital capacity?

The correct way the measure vital capacity is by using a spirometer.

It can also be estimated this way:

Vital Capacity can be measured with a string, calculator, ruler and balloon, believe it or not. Blow up the balloon and let it out a few times to stretch the rubber. Then take a very deep breath and blow out all the air that you can into the balloon. Tie it off. Pass the piece of string around the widest part of it to measure it. Using the ruler, measure the string. (My VC is very good, it's 4.2, and so my string was about 60cm long.) Divide the meaurement of the string by pi (if you don't have suitable calculator, you can divide by 3.14 on a standard calculator) and compare the number to this chart: Balloon diameter (centimetres:)

is your final number that you got by dividing by pi. Balloon diameter: Approximate vital capacity in litres:

8 0.3

9 0.4

10 0.5

11 0.7

12 0.9

13 1.2

14 1.4

15 1.8

16 2.1

17 2.6

18 3.0

19 3.6

20 4.2

Theoretical vital capacity:

Look for Vital capacity in Wikipedia for the formula. There are also online calculators.

Can two O positive parents have rhesus negative child?

No, group O means having no antigens (markers) on your red blood cells, therefore nothing to transfer to children.

Vicodin detection time?

3-7 days I have taken my prescribed vicodin 2 days prior to testing and came up negative. It really depends on the strength and how often you take it. In addition, the amount of fluids you drink directly affect the time that any opioid stays in your system. The more you drink water, the faster it's out of your system. This information comes from my personal experience and the advice from 2 RNs that I personally know.

Who can receive blood from an o- doner?

What does urobilinogen in the urine mean?

Urobilinogen refers to the presence of bilirubin in the urine. Bilirubin is an enzyme that comes from the liver, and if it shows up in urine, that typically means that a person has a serious illness. The illness could be anything from gallstones to anemia, since bilirubin in the urine could be caused by many different things.

What is monoacetylmorphine?

Ms contin

Oxycontin

Oxydone

Endone

Kapanol

Actually, MS Contin and Kapanol are the only oral drugs that are listed above that contain morphine. MS Contin and Kapanol are time-release versions. Another time-release version is Kadian. The other common oral drug that contains morphine is MS IR, which is the immediate-release version. Morphine is more commonly given in intravenious form, especially in a hospital setting, especially in a time-drip release form.

But the other drugs listed above do NOT contain morphine. OxyContin, Oxydone, Endone and another drug, OxyIR contain oxycodone, not morphine. Oxycodone is considerably more potent than morphine, in a dose-for-dose comparison. Percodan and Percocet contain a low-dose amount of oxycodone combined with aspirin or paracetamol (acetaminophen), respectively.
