طفل عمره ٦ سنوات يحك فتحة الشرج ليلاً، وتُشتبه الديدان الدبوسية. أي اختبار يُستخدم؟

A 6-year-old scratches his anal area at night and pinworms are suspected. Which test is used?

1. Sticky tape on the anus in the morning before bathing
2. A midstream morning urine test
3. A finger-prick blood sample taken in the evening at home
4. Abdominal ultrasound after a meal

Answer: A) Sticky tape on the anus in the morning before bathing. Pinworms lay eggs perianally at night, so tape is applied in the morning before bathing. Usually the whole household is treated, with hand and laundry hygiene.
