Why do I have to answer questions every time I donate?2019-11-15T13:22:15-06:00

All donors complete a new health history interview before each donation as a safety measure for both the recipient and the donor.

What if I am unable to donate after I have completed the Donor QuickPass™?2019-11-15T13:22:49-06:00

The Rock River Valley Blood Center realizes our donors sometimes face scheduling issues that can interfere with their planned donation. However, because your interview responses must be answered on the day of your donation, you will need to answer them again if you reschedule your donation for another day.

What if I lose my barcode receipt?2019-11-15T13:23:04-06:00

Please print, save or email your barcode receipt to yourself. If you lose your barcode receipt, you will need to complete a new health history questionnaire, either online or at the donation site.

Does Donor QuickPass™ ask different questions than a typical health history?2019-11-15T13:23:21-06:00

No. All blood donors are asked the same required health history questions regardless of the format used to answer them.

Am I required to answer all the questions?2019-11-15T13:23:57-06:00

No. You will continue to have the option to complete your health history interview one-to-one with a donor care staff at the time of your donation.

What if I’m not sure how to answer a question?2019-11-15T13:24:05-06:00

Using Donor QuickPass™, you can skip a question and review it with donor care staff at the time of your donation.

What if I answer a question incorrectly?2019-11-18T16:08:28-06:00

You will have the opportunity to go back and correct your answers at any time during the interview process by selecting the “Review Answers” button. If you have already completed the interview and printed your Donor QuickPass™ donor receipt, you should notify a staff member of your desire to change an answer.

Will I have to answer the questions again when I arrive to donate?2019-11-15T13:43:52-06:00

Typically, no. A staff member will scan your Donor QuickPass™ donor receipt and review your responses. In rare instances, you may have to answer the questions again at the time of donation if:

  • Your donor receipt is lost, or the bar code on the receipt cannot be read by the scanner.
  • Donor QuickPass™ is not completed on the same day as your blood donation.
  • If computer systems are down at the time of your donation.
What if I can’t access Donor QuickPass™ from my work computer?2019-11-15T13:44:44-06:00

The Rock River Valley Blood Center makes the Donor QuickPass™ available, securely through standard protocols, to all internet users.

What equipment is needed?2019-11-15T13:45:22-06:00

You’ll need high-speed internet access. A high-quality laser printer and paper are also recommended. Some ink jet printers may not provide a high-enough-quality barcode for the scanners to read.

Is Donor QuickPass™ the same as a donation appointment?2019-11-18T16:14:42-06:00

Donor QuickPass™ is not the same as an appointment to donate. If you would like to schedule an appointment at the donor center or for a blood drive, please visit schedule a donation online.

Does Donor QuickPass™ determine my eligibility to donate?2019-11-15T13:47:36-06:00

No, Donor QuickPass™ does not determine your eligibility to donate; that will be done at the time of your donation.

Are the responses kept confidential?2019-11-15T13:47:48-06:00

Yes, the only personal information printed on your donor receipt is your name. In addition, Donor QuickPass™ is designed to timeout after a period of inactivity so no one can access your confidential health history responses.

What are the benefits of using Donor QuickPass™?2019-11-15T13:48:40-06:00

Because you will have already completed your required health history questions prior to your donation, the process will potentially be shortened, reducing time away from work and personal commitments.

How far in advance can I complete my Donor QuickPass™?2019-11-15T13:48:49-06:00

Your health history questions can only be completed on the same day of your blood donation. Online interviews completed prior to 12:00 AM the day of donation will be invalid, and you will have to repeat the interview at the time of your donation.

How does it work?2019-11-15T13:48:57-06:00

You can access Donor QuickPass™ from RRVBC.org on the day of your donation. Using this web-based format – accessible from any computer with internet access – you are able to answer health history questions confidentially, print out a bar-coded receipt that contains your hidden responses, and bring it with you to your donation appointment.

What is Donor QuickPass™?2019-11-15T13:49:04-06:00

Rock River Valley Blood Center’s Donor QuickPass™ is a web-based, computer-assisted self-interview program that allows blood donors like you to answer required health history questions independently, in a private setting at a time that’s convenient for you.

What is blood?2017-08-29T16:22:14-05:00

Blood is a living tissue composed of blood cells suspended in plasma.

The cellular elements, red blood cells, white blood cells and platelets – make up about 45% of the volume of whole blood. Plasma, which is 92% water, makes up the remaining 55%.

What does blood do?2017-08-29T16:21:55-05:00

The average adult has 8 – 12 pints of blood traveling all over his or her body through the heart, lungs, arteries, veins and capillaries. Blood is an essential part of our bodies that transports oxygen, nutrients, and metabolic waste. In addition to all that, blood performs these functions:

  • Replenishes oxygen and removes carbon dioxide
  • Distributes essential nutrients to cells
  • Carries away metabolic waste materials for disposal
  • Recognizes antigens (foreign substances) and produces antibodies (immune defense mechanisms)
  • Clots cuts, wounds and scratches to prevent bleeding
How is blood used?2018-03-07T09:51:38-06:00

Blood and its components have many uses.

Hospitals stock some of the more common blood components used in emergencies, but usually blood products are not ordered until they are needed. They are kept at the Rock River Valley Blood Center until a hospital orders them.

Red cells can be used for 42 days after they are donated. They are used in the treatment of accident victims, to replace blood lost during surgery, to treat burn victims and to increase the blood’s oxygen-carrying capacity. They are also used in the treatment of anemia that can’t be medically corrected.

Platelets are stored separate from other components and must be used in the five days following the donation. They are commonly used to treat bone marrow failure, leukemia and cancer patients, low platelet count or other conditions causing abnormally functioning platelets.

Plasma has a much longer shelf life and is often frozen for later use. Once thawed, plasma is used during cardiac surgery, for burn victims, and to treat bleeding disorders. For example, bleeding disorders can occur in liver failure, when too much of a blood thinner has been given or when severe bleeding and massive transfusions result in low levels of clotting factors.

Plasma is often used to make therapies for bleeding disorders:

Factor VII concentrate is used in the treatment and prevention of bleeding episodes.

Factor VIII concentrate and cryoprecipitate are used by patients with hemophilia A (classic hemophilia), which is caused by a deficiency of factor VIII. Cryoprecipitate is prepared from plasma and contains fibrinogen, von Willebrand factor, factor VIII, factor XIII and fibronectin.

Factor IX concentrate is used by patients with hemophilia B (“Christmas disease”), which is caused by a deficiency of clotting factor IX.

Transfusions

A transfusion is a procedure that replaces the blood lost by a patient with the blood of a generous donor like you!

After you give your blood, while you’re snacking on cookies and showing off your arm wrap, your blood begins its journey to save lives! Through one donation, you can help save as many as up to 3 lives. No wonder RRVBC donors and volunteers feel so amazing. And, who ever thought saving lives could be this easy?
