Brenda K Hutson Posted March 18, 2017 Share Posted March 18, 2017 I am trying to create the conditions by which we can perform our Cord Blood Testing via automation. As we all know, cord blood specimens are not great. We were using a sterile screw top tube that they had used years ago, but in my efforts to see if we could automate it, we were able to locate sterile pink EDTA tubes for them to collect in. However, still getting them with clots. They found that if they filled them only 1/2 full (so quicker to get cap back on), the clotting was not as bad or frequent....but still no consistency. Our automation will run testing on Cord Specimens (Erytra), but we will not start it until when and if we can get them non-clotted (or at least where we can use an applicator stick and maybe just be taking out 1 small clot). Anyone out there successfully performing cord blood testing via automation? I can't imagine any analyzer would accept a clotted specimen so if you are, please share with me what your success is in getting non-clotted cord specimens. Thanks, Brenda Hutson, MT (ASCP)SBB Link to comment Share on other sites More sharing options...
MaryPDX Posted March 18, 2017 Share Posted March 18, 2017 We do. We also have Erytra and wadiana. Our cord blood samples are collected in either purple or pink edta tubes. All specimens get spun when received. If a cord sample needs to have testing performed, any clots are removed with applicator sticks and respun prior to testing.

Dansket Posted March 18, 2017 Share Posted March 18, 2017 Our cord blood samples are collected in red tops. They arrive in BBK usually with one giant clot. We remove the clot, centrifuge and test on ProVue. We stopped using EDTA samples because they usually had numerous small clots that were very time consuming to remove.

Guest Posted March 20, 2017 Share Posted March 20, 2017 Ah, so give up trying to "receive" non-clotted specimens.....just have to create them on our own. Either of you have issues because not all clots were removed sufficiently? Thanks, Brenda Link to comment Share on other sites More sharing options...
BankerGirl Posted March 20, 2017 Share Posted March 20, 2017 We test our cord bloods on the Echo by removing an aliquot of the cells from the EDTA tube. We can usually get clot-free cells this way. Any small clots are removed prior to analyzing. Link to comment Share on other sites More sharing options...

AMcCord Posted March 21, 2017 Share Posted March 21, 2017 We are running cord blood samples on an Echo for type, DAT and weak D. At first we were running cells collected from a red top tube - usually plenty of fall out cells in the bottom, but we had to wait for them to clot. I finally convinced delivery to collect in EDTA tubes using the sterile tube kit mentioned above. We very carefully remove any and all clots with applicator sticks and centrifuge. Working very well.

BankerGirl Posted March 21, 2017 Share Posted March 21, 2017 No problems so far. Link to comment Share on other sites More sharing options...
Laurie Underwood Posted March 21, 2017 Share Posted March 21, 2017 We run cord blood samples collected in a purple top EDTA on the TANGO. Check for and remove any clots with applicator sticks and centrifuge for 5 minutes before testing. Has been working fine. tbostock 1 Link to comment Share on other sites More sharing options...
lehooke1 Posted March 22, 2017 Share Posted March 22, 2017 We remove an aliquot from the primary container and rim the sample for clots prior to centrifugation. We use the Ortho Vision analyzers. Prior to that we used the ProVue. Link to comment Share on other sites More sharing options...
tbostock Posted March 22, 2017 Share Posted March 22, 2017 We also put our cord bloods on the Tango after removing clots. Works great. Link to comment Share on other sites More sharing options...
Sandy L Posted March 23, 2017 Share Posted March 23, 2017 We get our cords collected in a sterile Screw top tube, no anticoagulant. We've been testing on our analyzer for years now, 1st ProVue and now Vision. For some reason, after these clot and retract there is very abundant serum with lots of free RBC's. We just pull a small aliquot of serum and RBC's off, ream for clots (which are rare using this method) and then centrifuge. Link to comment Share on other sites More sharing options...

So are you placing that small amount of serum and RBCs, in a separate tube for testing? Brenda Link to comment Share on other sites More sharing options...

How did you validate the DAT coombs? Link to comment Share on other sites More sharing options...
