The role of urinalysis in acute tonsillopharyngitis
In acute tonsillopharyngitis, special attention is paid to the risks of developing late immunopathological complications caused by group A beta-hemolytic Streptococcus. To avoid missing conditions such as post-streptococcal glomerulonephritis, a strict monitoring schedule is regulated. Patients are necessarily prescribed a urinalysis and complete blood count on the 14th and 21st days from the onset of the disease, as well as electrocardiography on the 21st day.
Laboratory minimum when tuberculosis is suspected
According to clinical guidelines (level of conviction C, evidence reliability 5), children with suspected tuberculosis are prescribed an expanded diagnostic package. In addition to a complete blood count and biochemical blood test (total bilirubin, ALT, AST), this mandatory list includes a urinalysis, as well as microbiological sputum examination for Mycobacterium tuberculosis complex.
Monitoring children with scarlet fever
After recovering from scarlet fever, the child is placed under follow-up dispensary observation for 1 month. Such monitoring is due to the high risk of severe complications, including nephritis, myocarditis, and synovitis, which usually manifest in the 2nd–4th week of the disease.
- Examination timeframe: 7–10 days after discharge from the hospital.
- Scope of monitoring: clinical examination, ECG as indicated, and follow-up blood and urine tests.
- Further steps: if there are no abnormalities, the child is deregistered after 3 weeks; if pathology is detected, the patient is referred to a subspecialist (e.g., a nephrologist or rheumatologist).
Routine tests for irritable bowel syndrome
As part of diagnostics in children with clinical signs of irritable bowel syndrome (IBS), routine tests are used to exclude organic pathologies. Along with coprological examination, this list includes a urinalysis, which allows for a comprehensive assessment of the child's health status.
Toni-Scar-Tub: Tonsillopharyngitis (days 14–21), Scarlet Fever (7–10 days post-discharge), and Tuberculosis require mandatory urinalysis monitoring to rule out renal complications.
Class and exam questions
When is urinalysis performed in acute tonsillopharyngitis?
Follow-up urinalysis and complete blood count are prescribed on the 14th and 21st days from the disease onset for the early detection of potential post-streptococcal complications.
Why is urinalysis needed after recovering from scarlet fever?
Urinalysis is performed 7–10 days after discharge for the timely detection of immunopathological complications, particularly nephritis, which may manifest in the 2nd–4th week of the disease.
Is urinalysis included in the clinical minimum when tuberculosis is suspected?
Yes, general clinical urinalysis is included in the mandatory diagnostic package along with blood tests and sputum examination.
