Frequently asked questions
Is Anti-AT1R (angiotensin II type 1 receptor) high or low in PACVS?
Elevated. Studies summarised in the OSMF atlas report higher Anti-AT1R (angiotensin II type 1 receptor) in PACVS than in healthy controls. Source: Mantovani et al. 2024.
What symptoms is Anti-AT1R (angiotensin II type 1 receptor) associated with in PACVS?
The cited literature associates this marker with Lymphadenopathy, tonsillitis. These are population-level associations and do not mean the marker causes the symptoms.
Which test measures Anti-AT1R (angiotensin II type 1 receptor)?
It is measured as a blood test (serum / plasma / whole blood). Commercial laboratories such as CellTrend (specialty) list an orderable assay.
Is one abnormal Anti-AT1R (angiotensin II type 1 receptor) result diagnostic of PACVS?
No. No single biomarker is diagnostic of PACVS. Anti-AT1R (angiotensin II type 1 receptor) findings come from group comparisons, overlap considerably between patients and controls, and vary with study design, timing and comparison group. A result should be interpreted by a clinician alongside symptoms, history and other tests.
