Patients that have a previous type in the computer are drawn by a single authorized phlebotomist (physician, tech or RN). Patients that have not been previously typed are drawn as before but an additional signature is required on the requisition that verifies identification of the tube label and the patient's wrist band. The second signature must also be from authorized personnel (tech, physician or RN).

The original sample has only ONE ABO & RH performed, subsequent samples are crossckecked by the computer history for a match. We perform an immediate spin crossmatch on antibody negative samples for our "secondary" check before issue.

This also depends on whether a computer crossmatch is to be done and whether there is a previous record:

If a computer crossmatch is performed, the recipient’s ABO group must be

determined twice an ABO determination on the current specimen plus one of the following:

- second independent testing of the same specimen

- testing of a second correctly identified and labelled specimen. The

specimen may have been collected, identified, and labelled

concurrently with the current specimen.

- verification with results of previous ABO testing that are on file

Also, check out this AABB workshop textbook- it's old now but still makes interesting reading:

If we have historical data then we only do one ABO/Rh

If the patient is unknown to us we do 2 ABO/Rh on the sample sample. We would like 2 techs but we are staffed with only 1 tech during some parts of night shift, so that tech would have to due it twice.

We are a pediatric hospital.

If we have a historical blood type, we only do one ABO/Rh.

If it is a new patient to us, we repeat the ABO/Rh a second time on the same specimen. It would be nice to have a second separate specimen drawn, but with our baby and kid population, each draw is a major ordeal and we try to minimize blood draws as much as possible.

I just came from a CAP Inspector Training Seminar and was told that CAP was going to start requiring 2 typings on 2 different samples before anything but O cells could be given. Seems pretty stringent to me and wondered if others had heard this and what they thought.

For our hospitals that do not use a Transfusion Service (TS) armband (in addition to the hospital ID band). All patient's for transfusion that do not have a historical result, or valid result from an alternate source (lab), or autologous blood, will get a second specimen collected, different time from the intial specimen, for a repeat ABO/Rh. If there is another acceptable specimen available in the lab, i.e. hematology, that was collected at a different time from the intial specimen then that specimen could be used without "re-sticking" the patient.

For those hospitals that do use a TS armband in addition to the hospital armband for patient ID, The same specimen is retested if there is no historical or other acceptable means to compare the blood type.

We have found that errors occur both at specimen collection and at testing, so we designed our safety intitiative to capture either case.

We recently implemented the 2 specimen (historical or new draw and current specimen) different times / phlebotomist because of a sentinel event (non-fatality). With the variety of individuals who collect specimens for lab testing, we felt that this was the only way to prevent any future sentinel events. We explain to the patient the 2nd draw is for their safety. We only give O's until the 2nd type is available.

We get a second draw (if no previous history), or use another lab tube, different collector, for A,B,AB patient's. If a tube is erroneously Type O, there is no harm to the patient. This keeps the second draws to a minimum, and provides saftety. We give Type O until the second confirmatory type is completed.

At my facility if we had a computer type/historical type, one tech would perform one ABO/RH type. If it was a new patient with no history at all one tech would perform two ABO/RH types on the same specimen. A weak D was performed only once and noted in the computer, unless it was an OB patient
