Frequently Asked Questions
Registration: Our staff and volunteers will sign you in and go over basic eligibility and donation information. Our Counsellor will brief you about blood donation and you will answer some questions during a private and confidential interview about your health history and places you have travelled. You will complete donor registration which includes information such as your name, address and phone number.
Mini-Physical: We will check your temperature, pulse, Blood Pressure and your medical history will be assessed by the Medical Officer. Female donors will have their Haemoglobin value checked by a quick method which takes less than 3 minutes, to see if it is not less than 12.5gm%.
The Donation: You will be called to the blood donation room according to your turn. The actual donation takes about 5 to 10 minutes during which you will be seated comfortably. The process is safe and sterile. We will cleanse an area on your arm and insert a brand new sterile needle for the blood draw. It feels like a quick pinch and is over in seconds. Blood is collected into a closed system of interconnected bags. Staff and volunteers will be available if you have any queries. You may relax while the bag is filling. When the process is complete, a staff will place gauze over the phlebotomy site and ask you to keep your arm flexed at the elbow.
Refreshment: You will spend a few minutes enjoying refreshments to allow your body time to adjust, to be slight decrease in fluid volume. You cannot leave the refreshment area before 15 minutes as you will be under observation for any donor reactions. After about 15 minutes, your phlebotomy site will be observed for arrest of bleeding and a staff will place a band-aid at the site. You can now leave the room and continue with your normal daily activities. Enjoy the feeling of accomplishment knowing that you have helped save lives.

A single platelet donation can provide enough platelets for a full therapeutic dose for a patient in need. In fact, some platelet donations yield enough platelets for 2 or 3 therapeutic doses. By contrast, it takes 4 to 6 whole blood donations to produce a single therapeutic dose.
Many patients who need platelets are undergoing chemotherapy or organ transplant and have weakened immune systems. A platelet dose from a single donor reduces the patient’s exposure to multiple donors and is therefore preferred by many physicians.
Since the need is great for platelet donations, all blood donors are encouraged to consider platelet donations. It has been discovered that women who have previously been pregnant are more likely to carry antibodies that are believed to sometimes cause post transfusion complications for blood recipients. Hence, females who have previously been pregnant are better suited for red cell donation than platelet or plasma donations.
Platelet donation in a cell separator uses a disposable kit which is imported for the purpose. Since the kit used is costly, testing of the donor for infectious diseases is done beforehand so that wastage following discarding of a positive sample is avoided. Hence, unlike in whole blood donation, donors are tested for Infectious serology before the actual procedure and only donors who are serology negative are selected for the procedure. Since serology testing takes about 3 – 3½ hours, donors for pheresis should be brought to blood bank sufficiently early so that the procedure can be completed and product issued on the same day, if needed.
Previous donations:
Medication: Donors on Aspirin or aspirin-containing drugs should have a medication free interval of 3 days or 72 hours before they can donate platelets.
Body weight: For platelet donations, the minimum recommended body weight is 65 kg as against 50 kg for whole blood donation.
Precount:A pre-count of more than 2 lakh/mm3 platelets and Haemoglobin of more than 12gm % is required to be eligible for platelet donation.
Good forearm veins: One or more good veins are required for a successful platelet donation.
Blood Group: For platelet pheresis, the donors’ blood group and patients’ blood group should be identical.
Registration: Our staff and volunteers will sign you in and then go over the basic eligibility and donation information. You will answer some questions during a private and confidential interview about your health history and places you have travelled.
Mini-Physical: We will check your temperature, pulse, BP. Further, both arms will be checked for prominent veins and a suitable vein will be identified for phlebotomy. Now a small quantity of blood sample (usually 5ml) will be collected from a site different from the selected phlebotomy site and subjected to haematological evaluation and infectious serology testing. The haematological parameters are evaluated and samples with platelet count more than 2 lakh/mm3 and haemoglobin >12.5 gm% are selected for the procedure. Depending on the type of Infectious Serology Test employed, it may take 2 to 3½ hours for the result. Once the results are obtained, the procedure is scheduled for the same day itself or the next working day.
The Donation: One the day of the procedure, you should come prepared to spend a couple of hours in the blood bank. A disposable Kit (to be used for the procedure) along with a bag of anticoagulant solution will have to be purchased from the pharmacy. Loading the kit in the cell separator takes a few minutes only. The instrument draws blood from the previously selected phlebotomy site through a sterile tubing into the centrifuge bowl. The self-contained sterile tubing assures that your blood never comes in contact with the instrument.
Platelet donations may be a single or dual arm procedure depending on the collection device used. For a dual arm procedure, one arm is used for drawing the necessary blood components and the other arm is used for returning the unused components. For a single arm procedure, only one arm is used for both collection and return.
The Cell Separator collects about 400ml of blood at a time, processes it, separates platelets (or the desired component), and returns the unused components, which completes one cycle. The machine uses multiple such cycles (usually 6 or 7) to collect the desired number of platelets. The number of cycles may vary and is calculated by the machine depending on your pre-count, blood volume and the yield of the product required.
In most cases, the donation process will be complete in 90 minutes. You can watch TV, listen to music or read books during the process. When the blood components have been collected, the donation is complete and a staff person will place a bandage on your arm.
Refreshment: After donating, you should have a snack and something to drink in the refreshment area. You can leave the site after 10-15 minutes and resume normal daily activities. You are eligible for another platelet donation after 48 hrs, but not more than twice a week. Enjoy the feeling of accomplishment knowing that you have helped save lives.
