My little boy, who has been dealing with consistently enlarged lymph nodes for nearly two years now, is currently undergoing testing.
Every few months, we have him undergo a CBC, a differential, and a peripheral blood smear.
Why are the values on these results inconsistent? Even when drawing from the same blood sample, the findings seem to vary.
For instance, the automated counters frequently detect atypical lymphocytes—sometimes it’s 2, sometimes it’s 6, or even 8...
But they never show up on the CRP.
However, on the peripheral smear, rouleaux formations are always present.
Furthermore, the child lacks IgA (or has a negligible amount, specifically below 0.05).
While searching online, I read that this could pose a significant risk during a potential transfusion. Yet, when he underwent surgery under general anesthesia, neither the anesthesiologist nor the surgeon seemed to give it any thought; they didn't even note it in his records (whereas I, as a wannabe, had to formally sign off on a whole list of risks, including bleeding, since it was a neck surgery). How critical or potentially dangerous is this situation? Should it be highlighted in such circumstances?
(In the US, doctors are currently suspecting ALPS or are waiting to see if it develops into CVID, as his IgG fluctuates and his DN T-lymphocytes are right at or slightly above the upper Ref unit.)
An automated counter is by no means perfectly precise, particularly when dealing with a low number of detectable components. The same logic applies to the cytological examination. The most important thing is that the values do not deviate excessively from the overall clinical picture, which is why these tests are performed repeatedly.
It is likely due to anaphylaxis. However, a transfusion can be managed if the blood is prepared in advance.
You will only know for certain by consulting his primary pediatrician. It is certainly something that warrants close monitoring.
