There is an in-depth screening process before your blood will be given to a person in need. Prior to this, however, there are some basic requirements to meet:
Imagine you are critically injured in an accident, loaded into an ambulance and rushed to the hospital for emergency surgery. Odds are you may need up to 50 units of blood while the doctors work to save your life. Now imagine if there was no blood for you.
Next, you visit with a trained health professional to review your answers. At this time, they will also take your temperature and blood pressure, and check for signs of intravenous drug use. The bottom of the Record of Donation contains a number of "high risk activity" questions that are discussed.
Who Can Give Blood
When You Arrive at the Blood Donor Clinic
Hemoglobin levels will drop following a blood donation, but usually replenish within 56 days. If your hemoglobin does not meet the minimum criteria [link widoczny dla zalogowanych], you will be deferred from donation. Often, you will be eligible on your next visit. It may be low due to factors such as low dietary iron, normal blood loss during menstruation, or pregnancy. It may also be low due to anemia. If your hemoglobin levels are very low, a visit to your doctor to test for anemia and determine the underlying causes is recommended.

The Screening Process
Once at the clinic, you undergo a screening process to determine if you are eligible to donate. Each time you donate, you will go through the same procedures and be asked the same questions. This is to ensure that your blood is safe, and that it is safe for you to donate at that time.
The first thing you do is check in and receive information and brochures to read. Next, you meet with a CBS employee who will confirm your ID, current contact information, and donation history. They will then perform a hemoglobin or blood iron level test. This test is performed for the protection of the donors and to ensure the quality of red blood cells that will be donated.
you must be at least 50 kg (110 lb)you must not have donated in the last 56 daysyou must be in generally good healthyou must not be in a waiting period (for example: after dentist visits [link widoczny dla zalogowanych], new tattoo, or recovery from the flu)
The final step of the screening process involves the Confidential Unit Exclusion Label. The CBS employee will provide two bar-coded labels for you to choose from and leave the room. This allows you to either say "Yes [link widoczny dla zalogowanych], please use my blood" or "No, do not use my blood." No employees will know which sticker has been applied until it is later scanned at the la
Hemoglobin levels may be tested in two ways. In the initial test a lancet is used to prick your finger and a drop of blood is taken. It is then dropped into a vial with copper sulfate, and if the density is adequate, it will sink. If the results indicate that the hemoglobin levels may be low, a machine is used to determine the actual level in your blood.
Once it is determined that your hemoglobin level is adequate, you move on to the screening process. You are given a questionnaire about your health, recent travel activities and other pertinent information.
Luckily, Canadian Blood Services (CBS) is able to supply our nation with enough blood for the hundreds of thousands of people each year requiring blood or blood components following accidents, during surgery, or for treating cancer, burns, or blood-related diseases. In order to accomplish this, people like you must donate at one of their mobile or permanent clinics.
