Laboratory Testing

Before a doctor can diagnose a patient, laboratory tests such as blood work are required.

What is international normalized ratio?

The international normalised (UK spelling) ratio is a laboratory test that measures the amount of time it takes for blood to clot and compares it to an average. People on blood thinning drugs (such as Warfarin) would normally have this test done on a fairly regular basis. Check out http://www.heartrhythmfoundation.org/a-fib/INR_FINAL.pdf for more ino.

Is blood type o positive compatible with b negative?

The short answer is no. There are 3 blood proteans; the A protean, the B protean, and the RH protean. A person who gets blood with a protean not normally found in their body will have real problems. O blood is simply a way of saying that the blood lacks both A and B proteans. The - or + part of a blood type is just a way of saying if the RH protean is found or not. (+ if it is found - if not.) If a person with O+ blood gets b- blood they will get sick because the B protean will be attacked by the patient's body. (The body can't handle the foreign protean.) If a person with b- blood gets O+ blood they will get sick because the RH protean will be attacked by the patient's body. (Again, the body can handle the foreign protean.)

What is a U E blood test testing for?

A UE test refers to a blood test that checks Urea and Electrolytes. It is often ordered in patients who are generally unwell to screen for kidney failure and dehydration.

The test involves checking the blood levels of sodium, potassium, bicarbonate, urea, creatinine and often glucose. The results are only clinical signs and don't provide a definitive diagnosis because each finding can have several different causes. They can, however, point to a possible reason for the unwellness.

What if you have Ep cells in urine?

There are different types of epithelial cells that can be observed in urine. These may transitional, renal tubular, squamous, or neoplasia.

What is the Aim and objective of high throughput screening?

AIM: to reduce the time and to get results of large experiments of fine defined objectives.

What does ketones in the urine mean?

it means you either have diabetes , or you are suffering dehydration.

Ketones are formed when the body breaks down fat, so when you are starving and have not eaten enough your body starts breaking down the fat from the cells that is already stored and that is why ketones appear, they are a byproduct of this fat breaking.

Ketones can also appear from uncontrolled diabetes mellitus and rarely after drinking copious and significant amounts of alcohol.
The presence of abnormally high numbers of ketones in the urine (ketonuria) usually results from uncontrolled diabetes mellitus. Ketonuria can also be caused by prolonged diarrhea or vomiting that results in starvation.

What are haemotology fbc blood tests for?

An FBC (full blood count) or CBC (complete blood count) is used to examine all of the components of the blood. These components include red and white blood cells, platelets, and plasma.

What is a normal range for serum iron levels?

A normal range for serum iron levels is typically between 60-170 micrograms per deciliter (mcg/dL) in adults. Iron levels can vary slightly depending on the specific laboratory and reference values used.

Can an O positive mother and O positive father have A positive baby?

In short, no.

The four blood groups (A, B, AB, and O) describe the type of sugars that are present (expressed) on the red blood cells that carry oxygen. There are two types of sugar - A and B. If a person is AB, they express both A and B sugars, while type O individuals do not express any sugars. Since the father and mother each contribute one of their sugar genes to a baby, the possible combinations of genes and sugars are:

blood type AB = one A + one B

type A = A+A or A+O

type B = B+B or B+O

type O = O+O

Therefore, a type A baby must have at least one parent who expresses the type A sugar, although that parent can have either an AB or A blood type.

On the other hand, it is possible for two people with type A blood to have a child with type O, if both parents have the (A+O) combination and pass on the O.

This is also why determining the blood type is so important for transfusions - for example, you cannot give a person with type O blood any other type of blood. Since the type O recipient's immune system was not "trained" to accept the A or B sugars as a normal part of the red blood cells, it would think there is something wrong with the transferred cells and kill them.

Positive/negative is a different gene, and requires at least one parent to be positive for the child to be positive.

HTH!

What is the connection between amino acids and protein?

Amino acids are the basic structures of protein. Each type of protein depends on the arrangement of the amino acids. One inconsequential change can completely change the type of protein it is.

Is it ok to take a urinalysis on the day your period is ending?

Probably not. You shouldn't take a urinalysis test until your period is completely stopped for at least a day. If you take it, odds are you'll have abnormal results and your doctor may prescribe further tests or medications you probably don't need. Save yourself the hassle and reschedule. Your doctor will understand.

How do you randomize the patients in a clinical trial?

a computer does the randomizing in order to bypass human bias. Many, if not all of the people involved in the investigation will continue to be "blinded" to what the patient is actually receiving.

What is the clinical significance of Alcian Blue staining?

Alcian Blue staining is used in histology to selectively stain acidic polysaccharides, such as mucins and glycosaminoglycans, in tissues. It is particularly useful in diagnosing diseases characterized by abnormal mucin production, such as mucinous tumors. Alcian Blue staining can help pathologists identify these substances and aid in accurate diagnosis.
