- For sputum collection, drink a large volume of plain, noncarbonated water 8–12 hours before sampling.
- For throat (oropharyngeal) swabs, avoid eating or drinking, toothbrushing, mouth or throat rinses, chewing gum, and smoking for 3–4 hours beforehand.
- For nasal swabs, do not use nasal drops or sprays and do not perform nasal rinses for 3–4 hours before collection.
- When feasible, obtain swabs in the morning immediately after waking.
- Collect the specimen before starting antimicrobial therapy.
- Women: schedule urogenital swab collection or urine sampling before menstruation or 2–3 days after it ends.

- On the day of collection, do not perform oral hygiene before sampling.
Qanday foydalanish
Aerob va fakultativ anaerob ekish (odatdagi bakterial ekish) turli anatomik sohalardan olingan klinik namunalardan infeksiyaning bakterial sababchisini ajratib olish va identifikatsiya qilish uchun bajariladi. Natijalar maqsadli terapiyani tanlashni yo'naltiradi; zarur bo'lganda, organizm identifikatsiyasi bilan birga antibiotiklar va bakteriofaglarga sezuvchanlik sinovi o'tkaziladi. Test, shuningdek, davom etayotgan antimikrob davolash samaradorligini baholash uchun qo'llaniladi.
Cheklovlar
Insonlar teri va shilliq qavatlarda keng mikroorganizmlar hamjamiyatini tashiydi. Eng katta ulushi — taxminan 40% — me'da-ichak traktida joylashgan bo'lib, qolgan qismi teri, orofarenks, urogenital trakt va boshqa joylar bo'ylab taqsimlangan. Normal flora rezident (mavjud mikroblarning 90% gacha), fakultativ (10% dan kam) va o'tkinchi (tranzitor, 0.5% dan ko'p emas) sifatida tasvirlanadi. Mikroorganizmlar, shuningdek, patogenlik salohiyatiga ko'ra nopatogen (kasallik keltirib chiqarmaydi), opportunistik (odatda kichik miqdorda bo'ladi, ammo sharoit yaralganda yallig'lanish chaqirishi mumkin) va patogen (normal florada uchramaydigan chin patogenlar) toifalariga ajratiladi. Aerob va fakultativ anaerob florani bakteriologik ekish klinik namunadagi mikroorganizmlarning sifat va miqdoriy tarkibini, jumladan chin patogenlarni aniqlashni tavsiflaydi. Opportunistik organizmlar yuqori titrda aniqlanganda yoki patogen bakteriyalar identifikatsiya qilinganda, antimikrob preparatlarga — antibiotiklar va bakteriofaglar ham shu jumladan — sezuvchanlik sinovi ratsional terapiya tanlovini qo'llab-quvvatlash uchun o'tkaziladi.
