    Does anyone know of a program for training EMTs and Paramedics how to store and transport blood products as well as transfuse safely (which will probably be a rare task for any one individual)?  And then how about a process to assess that they are remaining competent?  I don't want to administer such a program as I already have a full-time job but would like to point them in the right direction or make clear what it would take to accomplish this.  We might consider providing liquid plasma if they can check all of the required boxes.  Our Air Ambulances already carry blood products, but they get a lot of opportunity to transfuse and are accustomed to following strict FAA regulations.  I think a lot of them are RNs also.  This would be ground ambulances.


    I think the EMTs for our helicopter service does transfusions.  We just switch out their LTWB O Positive units every 30 days or so.  The units hardly ever get used.  I will try to find out more information if I can.

    Hi, I was wondering where in the AABB technical manual states the timeline of repeating the antibody panel for a historical patient? Is it 2 weeks, 3 weeks, or every 3 days? Which is the most common and safest practice?



    A new sample shall be obtained from the patient within 3 days prior to transfusion in the following situations:

    1. If the patient has been transfused in the preceding 3 months with blood or a blood component containing allogeneic red cells.
    2. If the patient has been pregnant within the preceding 3 months.
    3. If the history is uncertain or unavailable. Day 0 is the day of draw.

    In patients with a history of previously identified antibodies, testing shall be capable of detecting and identifying the presence of newly formed clinically significant antibodies. Standard applies.


    When antibodies are detected, additional testing shall be performed to identify antibodies of clinical significance.

    That's odd. 

    I was under the impression (possibly false) that PayPal was only required for me.

    Anyhow, I just added Stripe payment processing.  When you get to the checkout, you can choose Stripe or PayPal.

    I appreciate your support!

    Thank you Cliff! Sorry, I didn't see this reply sooner. Thanks again

    Hello! I’m a long-time blood banker who has recently entered the world of microbiology. This forum has been such a great resource during my time in transfusion, so I’m hoping that the microbiology folks could answer a few questions related to WBC smears. I am interested in learning more about the workflow for this test and how these are prepared and read in different facilities.

    In your facility, are these typically done in microbiology or hematology?

    What stain are you using for WBC smears in your lab?


    We use the same stain we use for hematology slides, wright-geimsa. If we see WBCs, the result is a qualitative "present" or "none seen".  Usually, if there is an infection, it will be mostly neutrophils. 

  5. To whom this may concern, 

    Last year, Paypal canceled my account for some reason.  I called them but they gave me a vague explanation. So my premium membership wasn't renewed. 

    Is there another form of payment we can use? Like a credit card or something. Thank you.

    Hi fellow Epic users,


                                     Does your in basket thing alarm when you get an add on test?


    Mine does a little "ping" sound and then I click on it to see the add-on test(s).  You can have it silenced if you want. Then you will only see the basket icon blinking when you received add ons.

    If a patient's Immediate Spin Crossmatch is weakly positive (tube method), and the Antibody Screen and IgG Crossmatch (GEL) are negative, what is the next step to prove Blood Type compatibility? Advancing to pre-warmed method seems a waste of time since the GEL Crossmatch is already negative.


    Did you try checking for rouleaux? Sometimes rouleaux can cause the immediate spin XM to be positive but the Antibody screen negative.  All you need is saline replacement to see if its rouleaux. Or look at the cells under a microscope to check for rouleaux.

    No need to wash. We run Cord Bloods on our Ortho Vision.

    Could it be contaminated saline, perhaps?

    I would repeat using freshly prepared bottle of saline.



    I doubt it. We QC our saline in duplicate every day. Thank you for your input.

    I guess this may be caused by the Wharton's Jelly which can cause rouleaux formation of the cord cells. For the gel technique, it is good to test the adult cells without washing, but for the cord cells, maybe the Wharton's Jelly block  antigens on the cells' surface. I noticed that patients suffer from Multiple myeloma will not show false positive reaction in gel, but saddly I have not confirmed if there are false negative reactons.

    Yes, I was thinking wharton jelly too. This was a cord blood sample. Thank you
