it would normally mean that the human body does not have enough vital liquids and so sends a message to your brain and makes you become dehydrated. If this carries on you may feel faint because your organs cant work properly.
What are the neurological foundations of taste touch and smell?
I am unsure of the answer. I need help
Are all ECGS conclusion of any heart problems?
The ECG is to monitor the hearts rhythm and determine if their are any problems due to the waves.
Will you pass a drug test if you take antibiotics?
Antibiotics DO show up on a drug test - IF the tester is looking for antibiotics. If you mean "do antibiotics confuse the testing machine into thinking that I am taking an illicit drug" - then NO, they do not. The examiner will be able to tell the difference.
However, you should know that Drug testing examiners DO EXPECT you to be completely honest in answering ALL the questions they ask before you give the sample. For example, if you say that you are NOT taking any medications and Antibiotics DO show up; then you may be (probably could be) called to answer exactly why you either "lied" or misstated on the questions; and sometimes even need to produce a physicians prescription for the antibiotics you were taking.
In the case where a "testee" cannot accurately explain the contents of their own urine - there is always a suspicion/concern that that sample may not have come from the "testee."
it means: nodule-a rounded lump or knot; heterogeneous means "composed of unlike parts. Therefore a rounded lump composed of dissimilar tissues on the thyroid (gland) located in the base of throat region. may or may not require medical attention.
A mother is blood Type AB. What blood type will her children NOT have?
We are looking for the possible blood types of a baby.
Parental information:
- Mother type AB --she can contribute a A gene and a B gene
- Father is AB = baby can be AA, BB, AB -- Types A, B, AB
- Father is AA = baby can be AA, AB -- Types A, AB
- Father is AO = baby can be AA, BO -- Types A, B
- Father is BB = baby can be BB, AB -- Types B, AB
- Father is BO = baby can be BB, AO -- Types A, B
- Father is OO = baby can be AO, BO -- Types A, B
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the baby's inhibitory gene is turned "on", then it doesn't matter what type it is genetically, the offspring will test out as Type O.
I have O negative blood group I need blood which blood group is suitable?
O negative blood type can take only from O negative.
but in emergency cases if the O negative is not available, doctors give you O positive, and treat that with immune-suppressants.
When a MCH is high and an RBC is low what can cause this?
When a MCH and an RBC and WBC is low, what can cause this"
How quick does coca tea work and how long?
Coca Tea is is nothing like Cocaine, so it doesn't work or have long lasting effects. If you don't chew the leaves, it makes a very soothing tea that is used formedicinal purposes, to help with upset stomachand to help relieve altitude sickness. It is widely used in Central and South America, without being made into a narcotic. Since owning the Coca plant is outlawed for individuals in the US, Americans don't knowof it's many beneficial qualities.The Cocaplant is still used in stimulating beverages sold in America today, despite it's being illegal to grow, import or use by the average person.
How can you pass a hair follicle test after doing Vicodin?
You really can't. Hair tests are over 99% accurate and practically impossible to cheat. If you've used drugs in the last 90 days, they will find out.
A standard hair test uses the last 1.5 inches of hair, which goes back about 90 days. Longer hair samples can be taken to go further back in time, but that is atypical.
How long back do hair drug tests go?
For as long as you have had the hair. If you haven't had a hair cut in three months and did drugs 2 1/2 months ago, the proof will be there.
Hair drug testing is one of the important techniques to find presence of drug. Another drug testing includes blood, saliva, urine test etc
Can ab neg and o pos have a baby o neg?
No. The baby could have a negative Rh factor, but it would have either the A or B blood group.
What does low AG ratio calc mean?
- How is it used?
Total protein measurements can reflect nutritional status and may be used to screen for and help diagnose kidney disease, liver disease, and many other conditions. Sometimes conditions are first detected with routine testing before symptoms have begun to appear. If total protein is abnormal, further tests must be performed to identify which specific protein is abnormally low or high so that a specific diagnosis can be made.

When is it ordered?A total protein test is one component of a Comprehensive Metabolic Panel (CMP) that is often ordered as part of a routine health checkup. Total protein may also be ordered to provide general information about your nutritional status, such as when you have undergone a recent weight loss. It can be ordered along with several other tests to provide information if you have symptoms that suggest a liver or kidney disorder or to investigate the cause of abnormal pooling of fluid in tissue (edema).

What does the test result mean?Results of a total protein test will give your doctor information on your general health status with regard to your nutrition and/or conditions involving major organs, such as the kidney and liver. However, if results are abnormal, further testing is usually required to help diagnose the disease affecting protein levels in the blood.
Low total protein levels can suggest a liver disorder, a kidney disorder, or a disorder in which protein is not digested or absorbed properly. Low levels may be seen in severe malnutrition and with conditions that cause malabsorption, such asCeliac disease or inflammatory bowel disease (IBD).
High total protein levels may be seen with chronic inflammation or infections such as viral hepatitis or HIV. They may be caused by bone marrow disorders such as multiple myeloma.
Some laboratories also report the calculated ratio of albumin to globulins, termed the A/G ratio. Normally, there is a little more albumin than globulins, giving a normal A/G ratio of slightly over 1. Because disease states affect the relative changes in albumin and globulins in different ways, this may provide a clue to your doctor as to the cause of the change in protein levels. A low A/G ratio may reflect overproduction of globulins, such as seen in multiple myeloma or autoimmune diseases, or underproduction of albumin, such as occurs with cirrhosis, or selective loss of albumin from the circulation, as occurs with kidney disease (nephrotic syndrome). A high A/G ratio suggests underproduction of immunoglobulins as may be seen in some genetic deficiencies and in some leukemias. More specific tests, such as albumin, liver enzyme tests, and serum protein electrophoresis must be performed to make an accurate diagnosis.

Is there anything else I should know?Prolonged application of a tourniquet during blood collection can result in a blood sample that has a higher protein concentration than the rest of the circulation. This will mean that the test result for total protein will be falsely elevated (higher than the actual concentration in the circulation).
Drugs that may decrease protein levels include estrogens and oral contraceptives.
What does low osmotic fragility means?
Osmotic fragility usually (unless otherwise mentioned) refers to the ease with which Red Blood Cells (RBCs) undergo lysis in a hypotonic solution.
Before knowing what 'low osmotic fragility' means, one should know the concept of osmotic fragility. Different parameters, some of them related to the RBC and some of the extracellular environment have an effect on osmotic fragility.
Low osmotic fragility means that the RBCs have a resistance against undergoing lysis when suspended in solutions which are hypotonic. They undergo lysis only if the solution is extremely hypotonic.
In contrast, high osmotic fragility refers to the tendency of the RBCs to lyse even if the solution in which they are suspended in is mildly hypotonic.
As an example for low osmotic fragility would be thalassemia.
And as an example for high osmotic fragility, spherocytosis (a hereditary condition where the RBCs lose their usual biconcave structure and become spherical) causes increased osmotic fragility. i.e, It very easily lyses even at solutions which are mildly hypotonic...
p.s
Another interesting point to note is that in sickle cell anemia, the RBCs show increased mechanical fragility but decreased osmotic fragility. Elucidated by the fact that post-splenectomy the RBC lifespan increases.
