The Red Cross performs laboratory tests on blood products to qualify the products for transfusion and to protect the safety of the transfusion recipients. We do not provide diagnostic testing services for individuals. Additionally, a person must not donate blood in order to be tested since there is a danger of transmitting infections during the window period of the tests. Our community needs healthy donors. You can contact your local health department for AIDS testing.

How are chronic myeloproliferative disorders diagnosed?
Piedmont Heart Institute answered
In order to diagnose a chronic myeloproliferative disorder, your doctor will first conduct a thorough physical exam, looking for physical signs such as an enlarged spleen that are consistent with these types of disorders. Your blood will also be tested to detect any abnormally high levels of white or red blood cells. These blood tests can also check for diseases such as anemia and leukemia. Your doctor may also order a biopsy of the bone marrow. This procedure takes a sample of your bone marrow, which will reveal any abnormal levels of blood cells or signs of cancer. There are several types of this disorder, so your doctor may be looking for several different signs of abnormalities in the blood and bone marrow.
