The Benefits of Donating Blood. Medically reviewed by Alana Biggers, M. How Is Blood Drawn? In some cases, this is because the Red Cross immunohematology-reference laboratory may have previously tested their donation for sickle cell trait at the request of a hospital to fulfill a specific product need.
In these cases, the donor may have received a previous result of negative or positive. While the Red Cross will work to resolve many inconsistent results, portion will remain inconsistent. Carrying the sickle cell trait does not mean that an individual has sickle cell disease. Individuals who only carry the sickle cell trait are eligible to donate blood. This screening is performed on a blood sample given during the standard donation process to look for the presence of an abnormal type of hemoglobin, called hemoglobin S or sickled hemoglobin, a key indicator of sickle cell trait.
This means it is likely the individual inherited one sickle cell gene and one normal gene from their parents. If an individual receives a positive result, they should consult their medical provider to discuss their test results and pursue additional confirmatory diagnostic testing.
We are also looking into other possible funding sources. While, carrying the trait does not mean that an individual has sickle cell disease, health experts recommend that individuals with sickle cell trait be aware of their status and consult their medical provider on what it means for them.
In general, many individuals who carry the sickle cell trait have no medical problems related to sickle cell trait. However, these screening are not perfect.
As with all tests and screening, false results, or a screening result that incorrectly states the presence of abnormal hemoglobin, can occur. This is why those who receive a positive result are encouraged to consult their medical provider for confirmatory testing and discuss what their results mean for them.
Like other blood donation screenings, sickle cell trait screening is part of the blood donation testing process which occurs at no charge to the donor. In addition, this screening helps the Red Cross identify compatible blood types to help sickle cell patients more quickly.
Per standard donation procedure, only successful donations are sent to our laboratory for screening. This means that the individual is likely not a sickle cell trait carrier. It is important to note, that the Red Cross is not screening for other abnormal hemoglobin cells that can also cause sickling-- such as Hemoglobin C.
The Red Cross blood donation process at our blood drives and donation centers will not change. Blood, platelet and plasma donations will be screened using samples obtained at the time of donation and sent to a testing laboratory where the samples will also undergo routine screening and infectious disease testing.
These blood products will not be used to help sickle cell patients but can help other patients in need of lifesaving blood. Red Cross immunohematology-reference laboratories IRL have historically tested select donations for sickle cell trait at the request of a hospital partner actively looking to fulfill a specific blood product need.
This spring we are expanding our screening to include all blood, platelet and plasma donations from self-identified African American donors to allow us to identify compatible blood donations even faster to help patients in need of a blood transfusion. However, 51 percent of African Americans have type O positive or negative blood, in comparison to approximately 45 percent of white individuals.
Type O blood is most often in critical supply as it is most often needed by hospitals. Black donors play a vital role in helping meet the needs of all patients including—individuals who experience complicated childbirths, people fighting cancer, and accident victims being raced to emergency rooms. Donors will need to have a successful donation to receive sickle cell trait screening results.
Per standard donation procedure, only successful donations are sent to our laboratory for testing. How can I get my test results? This will provide the most expedient access to test results. If a donor has questions or issues with the Blood Donor App or portal functionality, please contact If a donor does not have internet service and therefore cannot use the two recommended channels, they may call the Red Cross Donor and Client Support Center 14 days after donation at to obtain their results.
This test is used to detect abnormal sickling hemoglobin cells or Hemoglobin S. If an individual receives a positive result, they should consult their medical provider to discuss their test results and pursue additional confirmatory testing. Both screenings are authorized for use by the FDA and are highly accurate. The Red Cross will not release your screening result or any other test result without your written permission unless required by law.
The Red Cross is only required to report positive sickle cell trait results in writing to donor. We do encourage those individuals who receive a positive sickle cell trait result to consult their medical provider to discuss their test results and pursue additional confirmatory testing.
This is why the Red Cross is currently testing only selfidentified African Americans for sickle cell trait as this time. The Red Cross plans to screen blood, platelet and plasma donations for sickle cell trait from these individuals through the end of However, you must wait 2 full days after taking aspirin or any medication containing aspirin before donating platelets by apheresis.
For example, if you take aspirin products on Monday, the soonest you may donate platelets is Thursday. The reason for antibiotic use must be evaluated to determine if the donor has a bacterial infection that could be transmissible by blood.
May have taken last pill on the date of donation. Acceptable if you are taking antibiotics to prevent an infection for the following reasons: acne, chronic prostatitis, peptic ulcer disease, periodontal disease, pre-dental work, rosacea, ulcerative colitis, after a splenectomy, or valvular heart disease.
If you have a temperature above Includes the Tdap vaccine. The second shot is administered months after the first shot. This distinguishes it from Zostavax, the live shingles vaccine, which is given as a single dose shot and requires a 4-week deferral. Complications may include skin reactions beyond the vaccination site or general illness related to the vaccination.
See how common or rare various types of blood are in the U. Whatever your blood type, we encourage you to donate. Everyone who is eligible can donate blood, but depending on your blood type, you're only able to receive certain types of blood, plasma or platelets. There are eight different blood types, and they're not always compatible with each other. Interestingly, people who have O-negative blood are considered universal donors for the entire population. When it comes to blood components, compatibility is the opposite of whole blood.
Donors with Type AB blood are the universal donors of platelets and plasma. There are no substitutes for blood, platelets or plasma—they cannot be manufactured. Patients in need of blood or blood products must rely on donations from people like you. Those who are hesitant about donating blood for the first time often find that the donation process is easy and that saving lives is deeply gratifying. There's a critical shortage of blood and blood products in the Los Angeles area and across the country.
You can save lives with just 1 pint of blood. Organizing a group of people to generously donate blood is a wonderful way to give back and help those in need. Recently donated blood?
