Skin tests and sinus X-rays are best for preclinical allergic rhinopathy diagnosis. Nasal tests and blocking antibodies aid long-term allergic rhinitis monitoring and treatment follow-up.

Identifying at-risk children is crucial for early intervention.
Current diagnostic tools vary in specificity and utility for different stages of the disease.
Purpose of the Study:
To evaluate the efficacy of various diagnostic methods for preclinical allergic rhinopathy.
To determine the most suitable tests for long-term allergic rhinitis monitoring and hyposensitization therapy follow-up.
Main Methods:
A cohort of 1620 schoolchildren was screened, with 370 identified as high-risk.
Included tests: skin prick tests, nasal examinations, immunoglobulin measurements, rhinomanometry, nasal provocation tests, blocking antibody assays, sinus radiography, and RAST (Radioallergosorbent Test).
Main Results:
Skin tests and sinus radiography showed higher specificity for preclinical diagnosis compared to RAST.
Nasal conductance, provocation tests, mucociliary clearance, and blocking antibodies proved adequate for long-term allergic rhinitis study and treatment follow-up.
RAST results were positive only in children with manifest symptoms in this cohort.
Conclusions:
Skin tests and sinus radiography are recommended for preclinical diagnosis of allergic rhinopathy.
Nasal function tests and blocking antibody measurements are valuable for monitoring allergic rhinitis and assessing treatment efficacy.
RAST may be less sensitive for detecting preclinical allergic disease in this population sample.
