What did @travelingterry actually say?
TravelingTerry shared a batch of functional medicine lab results and walked through them one by one. The short version: elevated T4, elevated Reverse T3, persistent thyroglobulin antibodies, high C-reactive protein, low omega-3 levels (specifically DPA), past Epstein-Barr virus (EBV) infection based on antibody results, and a panel of food sensitivities that included wheat, tomatoes, carrots, tree nuts, and egg whites.
Terry said the EBV results "indicate that there was a past infection and that I currently have the antibodies," and connected low DPA to cardiovascular and cognitive disease risk. They also flagged high CRP as linked to "increased risk for heart disease." Terry is not self-diagnosing or treating. They sent results to their PCP and have a follow-up scheduled. That context matters.
Does the science back this up?
Mostly yes, with important nuances. The EBV-Hashimoto's connection is real and increasingly well-supported. The CRP-cardiovascular risk link is legitimate. The omega-3 interpretations are reasonable but overstated. The food sensitivity panel is where things get complicated.
On EBV: a 2022 study by Bjornevik et al. in Science made headlines showing EBV dramatically increases multiple sclerosis risk, and research from Janegova et al. (2015, International Journal of Molecular Sciences) found EBV DNA present in thyroid tissue of Hashimoto's patients at significantly higher rates than controls. The mechanistic theory is molecular mimicry: EBV antigens may trigger an immune response that cross-reacts with thyroid tissue. So Terry's functional doctor ordering EBV antibody testing in a Hashimoto's workup is not fringe medicine.
On CRP: the association between elevated high-sensitivity CRP and cardiovascular disease risk is well-established. Ridker et al. (2002, New England Journal of Medicine) showed hs-CRP predicts cardiovascular events independently of LDL. However, CRP is nonspecific. Autoimmune conditions like Hashimoto's can elevate it without implying direct cardiovascular pathology.
What did they get wrong (or right)?
Terry gets credit for being careful with language. They didn't claim EBV caused their Hashimoto's. They said "it could have been a recent past or a long time ago," which is accurate, since EBV IgG antibodies persist for life after infection.
Where things get shaky: the food sensitivity panel. Terry describes results for wheat, tomatoes, carrots, hazelnuts, and egg whites as though these are diagnostic of food allergies or immune triggers. Most functional medicine food sensitivity tests measure IgG antibodies, not IgE. The American Academy of Allergy, Asthma and Immunology has explicitly stated that IgG food testing lacks clinical validity as a diagnostic tool for food allergy or intolerance (Carr et al., 2012, Journal of Allergy and Clinical Immunology). Elevated IgG to a food more likely reflects exposure, not pathology.
The omega check framing is also somewhat loose. Low DHA/DPA status does correlate with inflammatory and metabolic risk in population studies, but Terry's phrasing that it "can be a predictor of cardiovascular, neurological, and cognitive diseases" edges toward causation language that the evidence doesn't fully support at the individual level.
What should you actually know?
If you have Hashimoto's and are wondering whether your functional doctor's testing is legitimate, some of it is. EBV serology in autoimmune thyroid disease is a reasonable investigative step backed by emerging research. Omega-3 status testing has real clinical relevance for inflammation monitoring. CRP as an inflammatory marker is standard medicine.
But food sensitivity IgG panels are a genuinely contested area. Mainstream allergy specialists consider them unreliable, and acting on them can lead to unnecessary dietary restriction. If Terry removes tomatoes, carrots, and egg whites based on these results without an elimination diet with proper reintroduction protocol, they may be restricting nutrients without measurable benefit.
The Reverse T3 elevation is worth discussing with a physician. Some research, including work by Bianco et al. (2019, Endocrine Reviews), suggests Reverse T3 may reflect cellular hypothyroidism even when TSH appears normal, but this remains debated and is not standard clinical practice to treat in isolation.
The bottom line
Terry is doing something most patients don't: reading their labs, asking questions, and looping in a qualified PCP. That is the right approach. The Hashimoto's-EBV connection is scientifically legitimate. The CRP and omega findings are worth discussing with a doctor. The food sensitivity panel deserves more skepticism than it got here, not because Terry did anything wrong, but because IgG-based food panels have a weak evidence base and are widely oversold in functional medicine settings.
