Introduction

Core Value and Technological Evolution of the Standard

As my country's first national standard for urine biological sample collection, this standard fills the gap in the standardized management of urine samples for scientific research. Compared with clinical laboratory standards such as WS/T 348-2011, its innovation is reflected in:

Comparison dimensions	GB/T 38735-2020	Traditional clinical standards
Scope of application	Scientific research + clinical dual application	Clinical laboratory only
Sample type	7 categories of full process specifications	3-4 basic types
Quality control	Including nucleic acid/protein protection solutions	Conventional preservation only

Detailed explanation of key operating specifications

1. Sample container selection

The standard puts forward strict requirements for urine retention containers and dispensing containers:

Material safety: Inert and environmentally friendly materials must be used to avoid interference of dissolved substances with omics analysis
Special design: The volume of the timed urine container must be ≥4L, and a special sterile container is required for bacterial culture
Low temperature adaptability: The label material must withstand -196℃ liquid nitrogen environment

2. Key points for special sample collection

Case: Timed urine collection for children

A pediatric research project in a tertiary hospital requires the collection of 24h urine samples. Implementation points:

Use polyethylene collection bags to replace traditional containers
Use dual identification system (QR code + RFID)
Strictly record the urination time window (±5min error)

Implementation suggestions and common problems

Implementation links	Recommended plan	Common errors
Informed consent	Adopt a graded notification system	No permission for secondary use of samples
Sample repackaging	Freeze and store in 0.5ml aliquots	Freezing and thawing of the whole tube leads to repeated freezing and thawing
Quality Control	Establish Sample Acceptance and Rejection Standards	Ignore transportation temperature records
