The ABO group and Rh typeThe ABO group and Rh type must be determined for the blood of both the donor and the intended recipient. ABO group is determined by testing the RBCs with anti-A and anti-B reagents and by testing the serum with A1 and B RBCs. Rh type is determined with anti-Rh (anti-D): if the initial test of the donor blood with anti-D is negative, then that blood is tested by a method designed to detect weak D (Du). When either Rh test is positive, the blood sample label reads Rh positive. Conversely, when the tests for both D and Du are negative, the label reads Rh negative. It is not necessary to determine whether a patients RBCs are of the Du type because no harm results from transfusing Rh-negative blood.
How is blood group testing doneBasically, a sample of your blood is mixed with different samples of plasma known to contain different antibodies. For example, if plasma which contains anti-A antibodies makes the red cells in your blood clump together, then you have A antigens on your blood cells. Or, if plasma which contains rhesus antibodies makes the red cells in your blood clump together, then you have rhesus antigens on your blood cells. By doing a series of such tests it is possible to determine what antigens are on your red blood cells.
Other blood typesThere are many other types of antigen which may occur on the surface of red blood cells. However, most are classed as minor and are not as important as ABO and rhesus.
Blood GroupingThe blood group depends on which antigens occur on the surface of the red blood cells. The genetic make-up which you inherit from your parents determines which antigens occur on your red blood cells. Because of this fact a blood group test is sometimes used to help settle disputes about who is the father of a child. The blood group is said to be: A+ (A positive) if you have A and rhesus antigens. A- (A negative) if you have A antigens, but not rhesus antigens. B+ (B positive) if you have B and rhesus antigens. B- (B negative) if you have B antigens, but not rhesus antigens. AB+ (AB positive) if you have A, B and rhesus antigens. AB- (AB negative) if you have A and B antigens, but not rhesus antigens. O+ (O positive) if you have neither A nor B antigens, but you have rhesus antigens. O- (O negative) if you have do not have A, B or rhesus antigens.

The states testing showed that Susan Michelbacher was blood type O, Rhoades is blood type A, Albert Michelbacher is blood type A, and Harry Burke is blood type O. Susan Michelbacher was a nonsecretor (NS), as is Albert Michelbacher; Rhoades is a secretor (S), as is Burke. Thus, only Rhoades and Burke are secretors, but Burke is blood type O, leaving only Rhoades as an A secretor.
2010-03-09 CBC News - Health - Add diabetes to Ont. school policy: parentsBetz is concerned she will have to visit her daughters school daily to test her blood sugar levels and do insulin shots until shes old enough to do it herself. Currently, school staff in Ontario are not required to help diabetic students monitor blood-sugar levels or provide insulin injections. Accommodations: At the start of the school year, parents and the principal would agree to a health plan, including accommodations such as allowing the child to test their blood sugar in the classroom or eat or drink when necessary. Some Ontario families with school-aged children requiring medical attention for conditions such as Type 1 diabetes have major concerns about a health and education policy currently under review. - Diabetes policy 81 ontario ministry of health betz shauna insulin

2010-03-05 Researcher ready to test new diabetes treatment in humans Local news, sports, weather, blogs, opinion, crime, obituaries, business, directory, marketplace, education, high school, family, shopping,The mice used in the tests had a shortage of leptin. Most Type 1 diabetics have normal leptin levels. The amount of additional leptin needed to control blood sugar in people may induce significant side effects that are more damaging than those associated with insulin. Extra leptin could make it harder for a Type 1 diabetic to be aware of the dangerous condition of low blood sugar and make it harder to return low blood sugar to normal levels. DALLAS A longtime diabetes researcher at University of Texas Southwestern Medical School is setting up human tests for a new treatment he says might have fewer side effects than standard insulin therapy. Dr. Roger Unger, chairman of diabetes research at the school, is quick to warn a novel method that worked in mice with Type 1 diabetes may not help people.
2010-03-04 AMA Release Updated Prostate Cancer Treatment Guidelines : dBTechnoOne way to check for the presence of prostate cancer is to perform a PSA test, which looks for the presence of a type of protein in the blood of patients. The new AMA guidelines are to insure that doctors explain the pros and cons of a PSA test with their patients before any blood is drawn. This test is useful but not very beneficial when it comes to determining if a tumor is of an aggressive or harmful nature and sometimes leads to unnecessary treatment.
2010-03-03 PINC trial launched to test new treatment for pre-invasive breast cancerThis three-year clinical trial will test the effectiveness of the anti-malarial drug chloroquine in treating 90 women with ductal carcinoma in situ (DCIS), a type of breast cancer in which the cancer cells start in the milk ducts but have not yet become invasive and spread in the breast. Once the cancer cells start to spread in the breast and throughout the body, the condition is considered invasive and can often be fatal. Pre-cancerous cells have adapted to survive inside the milk duct without a blood supply and with very few nutrients. They overcome starvation through a process called autophagy. Its a way for a cell to make its own food and store it in a cookie jar. In the breast ducts, the DCIS cells use these cookies to survive and potentially spread. Simply put, chloroquine goes into the cells cookie jars and prevents the cells from using that food so that they eventually die from starvation," says Espina. Can a drug that has been used to treat malaria for years possibly be used to treat breast cancer before it becomes invasive Thats what researchers at George Mason Universitys Center for Applied Proteomics and Molecular Medicine (CAPMM) and Inova Breast Care Institute (IBCI) are trying to prove. - Cancer news cancer health medicines cancer research cancer treatments cancer studies cancer medicine types of cancer
