Does declining CBC matter, or only once fully out of range?
My 5 year old daughter has had 3 CBC / complete blood count tests, each essentially 6 months apart. In the span of this year, nearly all CBC metrics have decreased, to the point that on the graphed results nearly all metrics are smooth lines downward (smooth, continuous trends across 3 different test dates). Multiple metrics (WBC, RBC, hematocrit, neutrophils, and more) are nearly low enough to be lower than the reference range, but at this moment in time none are fully low. At the rate of decline, absolute neutrophils will be low within a month, WBC to follow soon (of course these trends can change).
My concern is if any of these trends continue then my daughter will within months be low on, well, all her actual blood counts. The only items not declining are MCH and MCHC. My daughter is suspected of having an immune or autoimmune issue and has a complicated medical history, is under the care of multiple specialists whom we do have great and open relationships with. Her rheumatologist today questions whether the declining CBC metrics are useful in themselves and indicated that we need to wait until they are fully out of range / not just borderline low. My gut tells me there is more diagnostic value to this and I don't want my child to suffer longer, but I am somewhat at a loss of next steps, and cautious to not get labeled an overly worrying and non-complying father.
Should we see a hematologist or another specialist? My daughter's doctors are amazing, truly, and so very caring and thorough in their own fields, but I worry there is some isolation that might limit their view. My daughter currently shrieks in pain regularly due to now having eye inflammation (traveling to a specialist hospital in a few days for a deeper workup on that) so I am admittedly looking for every angle and possible path forward. Thanks.

"Helicopter husband" would be me. I'm glad you had a supportive husband. Thanks for reaffirming that I am not overboard for asking for additional workup.
In pediatrics it seems there is somewhat of a tendency to dismiss kids, and while I didn't understand at first I've learned to deal with the "95%" idea. If only 5% of symptoms ever warrant more than time to resolve (maybe with a boost from antibiotics) then most of the time doctors can be correct dismissing everything! The whole "horses, not zebras" thing.
We had been lucky enough to score a next-day appointment (due to a cancellation) with a very well regarded pediatric pulmonologist who ordered labs and set all the wheels in motion going forward. And "lucky enough" that my daughter was so outwardly symptomatic that the doctor was able to see the severity. If it wasn't for that visit, I don't know if we would have been "elevated" to the "yes, this kid needs help" status.
What makes my blood figuratively boil is we tend to see only doctors within our local hospital network, because the network is very modern, well regarded, and has the latest and best records system. Any provider can simply click two buttons and see all tests, vitals, diagnoses, and more visually trended. Yet, until we entered the realm of specialists (also in network, but in a new and very well funded specialty center), every provider, while being kind and sympathetic, acted as if each occurrence was singular and in a vacuum. We literally had to bring paper printouts to show providers that we were not drug-seeking Munchausen parents! My point is not "poor us", but rather unless you have the time, resources, will, and sheer stubbornness it stands to reason that many health issues are diagnosed in teen and early adult years because only then is the patient taken seriously enough. Anyway, rant over.
Thank you so much for help and support - you are wonderful!
Thank you! This is very helpful and I will look into all these tests very soon. I'm about to pick up my daughter from camp and drive to Philly for an overnight stay - we have an appointment early tomorrow and what is a 40 minute drive in good traffic can be a 3+ hour drive during rush hour so we don't chance it.
Again, thank you so much for the insights and ideas.
One other thought to discuss with her Drs, particularly pulmonologist: when she starts kindergarten she will be exposed to so many germs, mostly respiratory, and she may benefit from a daily preventative antibiotic to ward off bacterial infections. It won’t help for viruses, so immunizations are important. However with immune deficiency, the antibody response to vaccines may be weak and not as effective as one would like. Trying to limit her exposure to sick kids is important but certainly not easy once kids are in school. If she’s been in preschool she may be already developing some tolerance to all the germs floating around! Please keep us updated.
Good morning, @lorenzom. Just wanted to pop in to see how your little girl is doing after her visit with the eye specialist. I hope her doctor was able to offer some relief from the pain she’s been experiencing. Sending a gentle hug.
