- Hydrate with plenty of plain, noncarbonated water 8–12 hours before sputum collection to aid expectoration.
- For 3–4 hours before oropharyngeal (throat) swabbing, do not eat or drink, avoid toothbrushing and mouth or throat rinses, and refrain from chewing gum or smoking.
- For 3–4 hours before nasal swabbing, do not use nasal drops or sprays and avoid nasal rinsing.
- When possible, collect swabs in the morning immediately after waking.
- Collect the specimen before starting antimicrobial therapy whenever feasible.
- Women: schedule urogenital swab or urine collection before menstruation or 2–3 days after it ends.
- Men: avoid urination for 3 hours prior to urogenital swab or urine collection.
- On the day of oral specimen collection, skip oral hygiene.
Qanday foydalanish
Aerob va fakultativ anaerob flora uchun bakteriologik ekish (rutin bakterial ekish) klinik ahamiyatga ega namunadan gumon qilingan infeksiyaning etiologik agentini ajratib oladi va identifikatsiya qiladi. Test antibiotiklarga sezgirlikni aniqlash (ekish va sezgirlik) orqali yo‘naltirilgan antimikrob terapiyani tanlashni qo‘llab-quvvatlaydi va organizmlarning yo‘qolishi yoki o‘sishining kamayishi orqali terapevtik javobni baholash uchun qo‘llanilishi mumkin.
Cheklovlar
Odam terisi va shilliq qavatlarida murakkab normal mikrobiota yashaydi. Eng katta ulushi — taxminan 40% — oshqozon-ichak traktida, qolgan qismi esa teri, orofarinks, urogenital trakt va boshqa joylarda taqsimlangan. Ushbu hamjamiyat ichida rezident mikroorganizmlar mavjud organizmlarning 90% gacha qismini tashkil etadi, fakultativ a’zolar 10% dan kamini, tranzitor flora esa odatda 0,5% dan ko‘p emasini tashkil etadi. Mikroorganizmlar shuningdek patogenlik potensialiga ko‘ra tasniflanadi: nopatogen turlar kasallik keltirib chiqarmaydi; opportunistik (shartli-patogen) organizmlar qulay sharoitlarda ko‘payib yallig‘lanishni qo‘zg‘atishi mumkin; patogen organizmlar esa birlamchi etiologik agent sifatida harakat qiladi va normal floraga kirmaydi. Aerob va fakultativ anaerob florani bakteriologik ekish klinik materialdan ajratib olingan mikroorganizmlarning sifat va miqdoriy tarkibini tavsiflaydi hamda patogenlarni identifikatsiya qilish imkonini beradi. Opportunistik organizmlar yuqori titrda aniqlanganda yoki patogen organizmlar ajratib olinganda, yo‘naltirilgan terapiyani ma’lumot bilan ta’minlash uchun antimikrob sezgirlik sinovi — odatda antibiotiklarga va, tegishli bo‘lsa, bakteriofaglarga nisbatan — o‘tkaziladi.
