Blood Donor

As clever as human, still don’t able to build a blood. If a patient lessen of blood or anemia on our body we need blood transfusion, this blood is get from many volunteer who give their blood. This blood then will process first using a process called as fractionation. This blood volunteer more found in developed countries, in under developing country and poor country we difficult to find a blood volunteer, why? This is because of rare of established supplies are limited and donor just give blood when the family or friends need a transfusion.

Blood donation also must fulfill the certain condition, should no contaminated with certain diseases like HIV and Viral Hepatitis. Beside some blood test, the donor also will ask about the medical history and given a short physical examination for sure that the donation have no risk to others.

The amount of blood will taken from blood donor for about 500 milliliters of whole blood. The tool to take out this blood can by manual tools or by automated equipment that only takes for specific portion of blood. The donor can give their blood every routine period, this is vary from several days to months that depend on the donate condition or country laws where the donation takes place.

The diseases that oblige as blood donor may vary:

• AIDS
• Hepatitis B
• Hepatitis C
• West Nile Virus
• Syphilis
• Malaria
• Rubella
• And Other Blood Diseases

Blood Test for Diabetes Diseases

People who have an indication of getting diabetes must be checked their blood glucose contains on their blood. A person who will take this test must fast before for about 12 hours usually from 9:00 pm to 9:00 am. Then he/she will take a blood sample for test the sugar blood contains.

In diagnosing diabetes, physicians primarily depend upon the results of specific glucose tests. However, test results are just part of the information that goes into the diagnosis of diabetes. Doctors also take into account your physical exam, presence or absence of symptoms, and medical history.

Some people who are significantly ill will have transient problems with elevated blood sugars which will then return to normal after the illness has resolved. Also, some medications may alter your blood glucose levels (most commonly steroids and certain diuretics, such as water pills).
The two main tests used to measure the presence of blood sugar problems are the direct measurement of glucose levels in the blood during an overnight fast and measurement of the body's ability to appropriately handle the excess sugar presented after drinking a high glucose drink. The standard of blood glucose test if contains value above 140 mg/dl on at least two occasions typically means a person has diabetes. Normal people have fasting sugar levels that generally run between 70-110 mg/dl.

An oral glucose tolerance test is one that can be performed in a doctor's office or a lab. The person being tested starts the test in a fasting state (having no food or drink except water for at least 10 hours but not greater than 16 hours).
An initial blood sugar is drawn and then the person is given a "glucola" bottle with a high amount of sugar in it (75 grams of glucose or 100 grams for pregnant women). The person then has their blood tested again 30 minutes, 1 hour, 2 hours, and 3 hours after drinking the high glucose drink.
For the test to give reliable results, you must be in good health (not have any other illnesses, not even a cold). Also, you should be normally active (for example, not lying down or confined to a bed like a patient in a hospital), and you should not be taking any medicines that could affect your blood glucose. The morning of the test, you should not smoke or drink coffee. During the test, you need to lie or sit quietly.

The oral glucose tolerance test is conducted by measuring blood glucose levels five times over a period of 3 hours. In a person without diabetes, the glucose levels in the blood rise following drinking the glucose drink, but then they fall quickly back to normal (because insulin is produced in response to the glucose, and the insulin has a normal effect of lowing blood glucose).

In a diabetic, glucose levels rise higher than normal after drinking the glucose drink and come down to normal levels much slower (insulin is either not produced, or it is produced but the cells of the body do not respond to it).
