Interval between whole blood and apheresis donation

[Shan Xue]

Currently after a person has donated whole blood, he/she needs to wait for 12 weeks before he/she can donate plasma/platelets.

With effect on 16 Aug 2005, the donation interval between a previous whole blood donation and subsequent plateletpheresis or plasmapheresis donation will be shortened to four weeks.

This is good news for regular plasma or platelet donors as they can donate whole blood once in a while without lengthening their next donation interval from 4 to 12 weeks.

i am O+ and the preferred donation type is whole blood. with the new donation interval, i can donate whole blood every 12 weeks while donating platelets every 4 weeks :D

On behalf of Dr Tan, I also would like to take this opportunity to inform
you that the donation interval between a previous whole blood donation and subsequent plateletpheresis or plasmapheresis donation will be shortened to four weeks with effect from 16 Aug 2005.

Hi, I was reading this leisurely and woul like to correct a "mis-quotation"

The correct information is: The waiting period in between whole blood donations and whole blood and pheresis donation is 12 weeks. In between pheresis donations is 4 weeks. i.e. If one donates whole blood now, he has to wait 12 weeks to make the next donation. If he makes a pheresis donation, then he only needs to wait 4 weeks for his next donation where he can choose to make either a whole blood or pheresis donation. If he makes a whole blood donation, then his next due is in 12 weeks. If he makes a phersis donation, then his next due is in 4 weeks.

Hi,

i think it is not a misquote unless the rule has changed again. i donated whole blood on 30 Jul 05 followed by platelets on 01 Sep 05, both at HSA blood bank.

[Cecilia Tan]

Hi, Thanks so much for the exchange. Seems I am one step behind you. You are right. The interval between a whole blood and pheresis donation is shortened to 4 weeks. If a donor alternates between whole blood and pheresis donations, he/she can give up to 12 times a year. This is such good news. Let's hope this will help more to come forward to give regularly.

Cheers

yes, this is very good news. it allows O+ and A+ donors to donate whole blood which is the preferred type by blood bank, get a break from the long duration of donating platelets every 1 out of 3 donations, and yet without having to lengthen the donation interval (can still donate every 4 weeks). previously, once i donate whole blood instead of platelets, i got to wait 12 weeks b4 making any donation. now just need to wait 4 weeks :D

hmm, let say now i am on whole blood donation, after whole blood donation, must wait how long before i can donate platelet? and after donate platelet must wait for how long before i can donate whole blood again?

[Shan Xue]

after whole blood donation, must wait how long before i can donate platelet?


4 weeks if you donate at HSA or NUH blood bank.



and after donate platelet must wait for how long before i can donate whole blood again?


4 weeks if you donate at HSA or NUH blood bank.

thx for the information :)

this topic is two yrs old. Does someone know how is it now? I mean, from whole blood donation till apheresis.
The previous design of HSA website had a table with previous->next donation intervals. Now they changed it and I cannot find this info.

[Shan Xue]

after donating whole blood, you need to wait for 8 weeks before you can donate apheresis.

[DrStoooopid]

after donating whole blood, you need to wait for 8 weeks before you can donate apheresis.


If it was a double red proceedure, you have to wait 112 days.

However, that being said, you CAN donate in an emergency with what they call "Limited Exposure"...in the event someone were to need granulocytes, or some other specialized cell. (or say for example, you're a rare donor.)

Hi! :)

Not sure if anyone had mentioned this before but if you have high Iron Count, you can donate whole blood every 10 weeks.

I had done this a few times now and am trying to maintain this schedule due to some personal reasons. :p

Actually, it is meant for regular donors who would like to advance their blood donation due to travel or vaccination. The minimum interval between donation is 10 weeks but the minimum hemoglobin criteria will be >13g/dl instead of the normal 12.5g/dl. For donors who donate regularly, they might want to follow the 12 weeks interval in order not to be disappointed by the possible deferral due to "low" hemoglobin.

Yeah, it's exactly what I was on Friday. I was 10w2d and I wanted to advance because of overseas travel. They told me that thing about hemoglobin level of 13. Guess what? My Hg was 11.8 :( Never been below 13 before! Looks like the 24/7 work on PhD thesis was not that easy...

[Shan Xue]

If you donate whole blood regularly, do take the iron supplements given by the blood bank. Alternatively, do whole blood donation 2 times a year and do apheresis donation in between. This will give your body time to recover the hemoglobin level.

You can ask the nurse for your historical hemoglobin level, so that you can monitor whether it has been dropping.

I realised it took me 5 months to fully recover my hemoglobin level. My steady level is about 14.8. After whole blood donation, it will drop and it takes about 5 months to fully go back to 14.8.

My recent hemoglobin record:

4 May 07: Whole blood donation. Hemoglobin = 14.8
30 Jun 07: Platelet donation, Hemoglobin = 13.3
4 Aug 07: Platelet donation, Hemoglobin = 14.0
5 Oct 07: Platelet donation, Hemoglobin = 14.8

Yeah, I think stress do affect. There was a period where my hemoglobin level hovers around 12.5 without increasing. After I come back from a relaxed Thailand organic farm trip, taking all the healthy food and relaxed mood, my hemoglobin level recover to 14.9 within 1 to 2 months.

This is a record of my hemoglobin level then:

7 Mar 06: Platelet donation, Hemoglobin level = 12.6
8 Apr 06: Platelet donation, Hemoglobin level = 12.6
6 May 06: Whole blood donation, Hemoglobin not measured
16 May 06: Hemoglobin= 12.3 (measured at polyclinic lab test)
3 Jun 06: Platelet donation, Hemoglobin level = 12.5

Went to Thailand organic trip

11 Jul 06: Platelet donation, Hemoglobin level = 14.9

[Shan Xue]

now after donate whole blood, need to wait for 8 weeks before can do apheresis donation.

Ya, I have to follow the 10 weeks schedule due to personal reasons which I had kinda completed recently (ya, been slacking on donating blood since a few years ago and only pick up again more than a year back when I discover the "ease" of just donating at the Blood Bank). Anyhow, always had successful donation as I manage to maintain a high count. ;)

Am planning to go back to the 12 weeks schedule after this year.
