Reference interval for 24-hour urinary protein excretion in uncomplicated women with twin pregnancies.

ABSTRACT:

Background

The study of 24-hour urinary total protein (24-h UTP) excretion is an essential parameter for the assessment of renal function and early detection of pregnancy complications. However, data on reference interval for 24-h UTP in women with twin pregnancies are scarce.

Objective

We aimed to establish the reference interval for 24-h UTP excretion in women with twin pregnancies and compare it with that in women with singletons.

Study design

A total of 12,633 participants with singletons or twin pregnancies were recruited. They were instructed to collect standard 24-hour urinary samples. Information was extracted from the electronic medical record. The nonparametric percentile method was used to determine reference interval for 24-h UTP excretion during different
