Qanday foydalanish
24 soatlik siydikdagi kreatinin testi buyraklarning ekskretor va filtratsion funksiyasini baholash hamda mavjud buyrak kasalligi bo‘lgan bemorlarni monitoring qilish uchun qo‘llaniladi. Shuningdek, vaqt bo‘yicha (24 soatlik) siydik yig‘malari yetarliligini tasdiqlaydi. Siydikdagi kreatinin boshqa siydik o‘lchovlari uchun, natijalar bir gramm yoki bir millimol kreatininiga nisbatan berilganda, normallashtiruvchi omil sifatida xizmat qiladi.
Cheklovlar
Kreatinin mushak kreatini va fosfokreatinidan nisbatan barqaror tezlikda hosil bo‘ladi va buyraklar tomonidan minimal tubulyar qayta so‘rilish bilan chiqariladi. Siydikdagi konsentratsiyalar zardobdagiga nisbatan bir necha tartib yuqoriroq. Muayyan shaxsda 24 soatlik siydik bilan kreatinin ajratilishi nisbatan barqaror bo‘lib, mushak massasi bilan korrelyatsiya qiladi; jins va yosh bo‘yicha kutiladigan farqlar mavjud. Qon zardobidagi kreatinin va 24 soatlik siydikdagi kreatinin bir vaqtda olinganda, glomerulyar filtratsiya tezligini baholash uchun kreatinin klirensi hisoblanishi mumkin. Vaqt bilan o‘lchangan siydik kreatinin chiqishi ozgina o‘zgarishi sababli, u 24 soatlik siydik yig‘malarining to‘liqligini baholash va oqsil yoki albumin kabi boshqa siydik analitlarini normallashtirish uchun qo‘llaniladi.
