The granulocyte percent in your complete blood count is high what does this mean?

The normal range for granulocyte percentage is 45.5 - 79.7%, which translates into a normal granulocyte count of 2.2 - 8.8 x 10^3/uL. Granulocytopenia is an abnormally low concentration of granulocytes in the blood. This condition reduces the body's resistance to many infections. Closely-related terms include agranulocytosis (no granulocytes at all) and neutropenia (deficiency of neutrophil granulocytes). Transfusion of granulocytes would have been a solution to the problem. However, granulocytes live only ~10 hours in the circulation (for days in spleen or other tissue), which gives a very short-lasting effect. In addition, there are many complications of such a procedure. If you have a high percentage be happy!!!cheers

What does the ab positive blood type mean?

A, B, O Blood

Blood is labelled in lots of ways, but the commonest is by a letter - A, B, O.

The letters refer to a marker that's found on red blood cells. We inherit these markers from our parents. We all inherit one marker from our mother and one from our father. Therefore we each inherit 2 types of red blood cell. A and B markers take precedence over O markers, but are equal to each other. This is because O isn't actually a marker or a letter - it's a zero. O people don't have a letter marker on their red blood cells.

It works like this -

If I inherit either two A markers, or one A and one O, then I'm an A (A takes precedence over O).

If I inherit either two B markers, or one B and one O, then I'm a B (B takes precedence over O).

If I inherit one A and one B, then I'm AB ( A and B are equal)

If I inherit two Os, then I'm an O (and don't have any letter markers on my blood).

These markers don't matter as long as we're healthy, but they matter a lot if we're not.

The markers are how the body's immune system recognises it's own blood from anything else. If the immune system sees a marker that it recognises on the blood cells, then that's fine and the immune system leaves them alone.

But, the immune system sees a marker that it doesn't know, then you've got a big problem. This is why blood transfusions have to be matched by blood type. If you give someone with A blood a bag of B blood, their immune system will see the B marker, won't recognise it and will attack the new blood and destroy it. Same for an O who is given either A or B - their immune system won't recognise the A and B markers and will attack and destroy the blood.

But, because O blood has no markers on it, you can give this to anyone - no markers means nothing for the immune system to see or attack. And people who are AB can receive any type of blood, because their immune system will recognise A markers or B markers and will leave them alone.

When can an elevated white blood count occur?

Four reasons that your white blood count might be high are:

* An increased production of white blood cells to fight an infection * A reaction to a drug that enhances white blood cell production * A disease of bone marrow, causing abnormally high production of white blood cells * An immune system disorder that increases white blood cell production

Do antidepressants show up on urine tests?

In depth review of drugs that cause false positives

Amphetamine/Methamphetamine

The active chemical of some medication will be metabolised to amphetamine, this will cause positive amphetamine/methamphetamine test results. Eg Adderall contains a mixed amphetamine salt widely prescribed as a psycho-stimulant medication for attention deficit hyperactive disorder, or ADHD, or ADD, and use of such medication would cause a positive amphetamine test.

In 2002 the Food and Drug Administration in the USA approved eye drops which contained hydroxyamphetamine and tropicamide. Although amphetamine is metabolised to hydroxyamphetamine, hydroxyamphetamine is not metabolised to amphetamine. Therefore, use of such products should not cause a positive (non-negative) amphetamine test result.

Drugs that may cause false positive to amphetamines include,

Diet pills (Amfepramone, Amphetaminil, Clobenzorex, Benzphetamine, Fenfluramine, Fenproporex, Mefenorex, Obetrol, Phentermine)

Attention deficit disorder medication (Ritalin, Dextroamphetamine, Adderall, Benzedrine, Pemoline, Pemoline)

Cold medication (pseudoephedrine (old sudafed), Vick’s Inhaler, Promethazine, Allerest, Bromphenlramlne, Dimetapp (loratadine), Efidac, Phenylephrine, Sinarest)

Antidepressants (Bupropion, Fluoxetine)

Blood pressure tablets (Labetalol)

Asthma medication (Inhalers, Ephedrine, Primatene-M, Tedral)

Antidepressants (Wellbutrin, Desipramine, Selegiline, Trazodone)

Parkinson’s disease medication (Amantadine, Deprenyl, Eldepryl)

Malaria treatment (Chloroquine)

Schizophrenia Medication (Chlorpromazine, Fluspirilene, Quetiapine)

Anti-inflammatory (Famprofazone)

Eye drops with Pholedrine

High blood pressure medicine (Labetalol, Procainamide)

Antihistamine (Mepyramine, Phenegan-D)

Gastroesophageal reflux disease medication (Ranitidine)

What does TSH stimulate?

Like other hormones of the anterior pituitary (adenohypophysis), TSH is stimulated by a releasing hormone produced in the hypothalamus. This releasing hormone, TRH (thyrotropin releasing hormone) travels down the pituitary stalk and stimulates the thyrotrope cells there, via the portal circulation of the pituitary.

How long does toradol last?

Toradol is an NSAID, or non-steroidal anti inflammatory drug. It is NON-NARCOTIC, meaning it is unscheduled in the United States and not against the law to possess it or have it in your blood or urine (aside from maybe needing a prescription to obtain it in the first place). But to answer the question, like ibuprofen and naproxen with which it is closely related, it should stay in your system for a period of up to 7-10 days, but being it is non-narcotic, there is no active metabolite it converts to in your body which can be easily tested for with, say, a simple urine or blood test. (note this is NOT legal advice)

How long to pass drug test after taking percoset?

In general Percocet remains in the system for approximately 72 hours, unless you have been using over the prescribed dosage. If you have a prescription for a pain then taking a drug test should not be an issue. Remember honest is the best policy. If you have a drug issue speak to your employer about treatment and not just try to dodge urinalysis.

If i was to take niacin drink vinegar and drink cranberry juice will i be clean for a drug test?

No liquid will help remove marijuana from your system. Marijuana is not water-soluble, but fat-soluble. It stores itself in your fat cells. Since fatty substances are not water soluble (think about what happens when you mix oil and water) drinking liquids will do nothing to clean your system of weed.

How much suboxone will show up in a drug screening?

Suboxone does not show up in drug tests. It only shows up if they specifically test for it, which my doctors say is very rare.

Where are LH and FSH produced?

Gonadotropic hormones FSH (Follicle stimulating hormone) and LH (Luteinizing hormone) are produced and secreted by the gonadotrophs in anterior pituitary.

These are the trophic hormones that act on the ovaries and testes. Required for ovulation, spermatogenesis, biosynthesis of estrogens and androgens. They are also used therapeutically to promote fertility.

Their secretion is regulated by the hypothalamus GRH (gonadotropin releasing hormone), where GRH stimulates the release of FSH and LH and FSH and LH feedback and decreases levels of GRH release. Estrogens and androgens also feedback and inhibit the gonadotrophs in the pituitary and feedback on the hypothalamus.

Is 3.09 tsh level high or low?

It is a controversial area. The upper limit of normal TSH values is 3 or 5 depending on the different recommendations made by different professional thyroid associations and on individual labs.

So, a TSH level of 3.09 is usually considered normal but it may sometimes be seen as too high. It definitely isn't considered low. If you are already taking thyroid hormones for hypothyroidism and you still feel unwell then increasing the dosage may be justified.

However, if you live in the UK and haven't been diagnosed with hypothyroidism even if you have thyroid antibodies then good luck trying to persuade anyone to prescribe T4.

Why do researchers use placebos and double-blind designs?

Researchers use placebos to test the effectiveness of the drug on trial.

Can a rh positive father have a rhs negative baby?

Yes, it is possible. There are two genetic alleles that together determine whether a person is Rh positive or negative. It is the combination of these alleles within the parents that determine the child's Rh status.

In this case, both mother and father are positive so their alleles can only be ++ or +-.

The possible combinations are determined by taking one allele from one parent and combining it with an allele of the other until all combinations are made. Positive is the dominant allele so combinations of ++ and +- are considered Rh positive whereas -- combinations are negative.

The possible combinations are:

++ which would be an Rh positive baby

+- which would be an Rh positive baby

-- which would be an Rh negative baby

So yes, it is possible.

How long does ethyl alcohol stay in a body?

For driving, you should leave 1 hour per drink. So if you have 10 drinks, wait 10 hours, etc.

Also, when drinking, to avoid a hangover have one glass of water to every clear drink (e.g. vodka) and two glasses for every dark spirit (e.g rum)

How does the cardiovascular system deliver oxygen and nutrients to the body?

through the heart, the heart has sides to it, the left and the right. The right side pumps blood to the lungs in order for oxgyen to be produced, but the left is the most strongest side because it needs to pump all the oxygenated blood around the body to its organs.

How long can alcohol be detected in you urine blood or on your breath?

Alcohol in breath dissipates quickly but not in urine, where it can be detected for about three days.
