Problems solved by technology

Although medical inspection analysis technology and information technology are becoming faster and more standardized, the intelligent audit of the analyzed test results is still in its infancy and is still in a weak link. Advantage
The utilization rate of automatic audit in domestic laboratories is not high. In recent years, some automatic audit systems for biochemical immunity have been developed and used in China. Only some large hospitals use them, and there are not many types of automatic audit rules set, which cannot cover pre-analysis and analysis. Post-analysis process, unstable quality, low passability, poor accuracy

Embodiment 1

[0074] A total of 895 urine samples from healthy individuals were collected from the physical examination center and used to establish the reference interval for the automated urine formed component analyzer. No urinary system-related diseases were found in all healthy persons, and no abnormalities were found in important tissues and organs such as the heart, liver, lung, and brain. Physical examination items were normal. Among them, there were 511 males and 384 females, aged 20 to 83 years, with a median age of 43 years. After calculation by software, the normal adult reference interval is obtained.

[0076]

[0077]

[0078] Urine testing, especially dry chemical testing, has unavoidable interference, so combined urine analysis techniques complement each other, and finally check and report under a microscope, which is currently a widely recognized and used process. ...

Embodiment 2

[0115] for example:

[0116] 1. A patient, female; the urine routine examination results are as follows: image 3 :

[0117] Among them, since the UF white blood cell is 798.5 / ul (level 3), and the dry chemical LEU500 (3+), the rule of "WBC≥1 level & LEU≥1+ & the difference between the two levels <2 level" in the re-examination rules is triggered, then it can be automatically Audit report issued. If according to the previous working method, the specimen needs manual microscopic examination, and can only be issued after manual review.

[0118] 2. For a patient, the urine routine examination results are as follows: Figure 4 :

[0119] Among them, because the patient’s UF red blood cell is 31 / ul (RBC±, grade 0); the dry chemical BLD is 0.03 (±, grade 0), and the UF red blood cell morphology information alarm is inhomogeneous; trigger “RBC=0 grade&dry chemistry= Grade 0 & (heterogeneous or mixed red blood cells)" requires manual microscopic examination before reviewing and i...

Embodiment 3

[0121] From January 2018 to March 2018, a total of 2,803 urine samples were collected from patients at the Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences (Hospital A), the Cancer Hospital of the Chinese Academy of Medical Sciences (Hospital B) and the Guang’anmen Hospital of the Chinese Academy of Chinese Medical Sciences (Hospital C). For the screening and establishment of re-examination rules and review rules, covering multiple clinical departments of nephrology, urology, tumor, traditional Chinese medicine, obstetrics and gynecology, blood, endocrinology, geriatrics, ophthalmology, ear, nose and throat, oral cavity, skin, etc., aged 5 to 97 , with a median age of 55. Urine retention standard is based on the 4th edition of "Clinical Laboratory Operation Procedures" [5] 30 to 50 urine samples were selected from each of the 3 hospitals within 2 hours after submission [6] , each specimen is required to be 10ml. The Sysmex UN2000 urinalysis as...

Abstract

The invention discloses a clinical laboratory urine routine examination automatic auditing system and a method. According to the method, a computer software-hardware system is used for programming a plurality of re-examination rules and an auditing rule for forming a re-examination and auditing rule executing module; automatic auditing is performed on examination results of various clinical urineroutine examination items; the examination results of the clinical urine routine examination items are transmitted to an automatic auditing unit after re-examination rule determining for performing automatic auditing; if an auditing rule cannot pass, the examination results are transmitted to an artificial auditing unit; and through auditing processing of an automatic auditing unit or an artificial auditing unit, an examination report is generated. According to the clinical laboratory urine routine examination automatic auditing system and the method, through reasonably setting the re-examination rules and the auditing rule, the whole examination process which comprises a before-analysis period, an in-analysis period and an after-analysis period can be covered, thereby realizing high passrate, high accuracy and high stability of the automatic auditing system. The system and the method further have advantages of greatly improving auditing efficiency, shortening examination result report time TAT, reducing error rate, reducing technical difference between employees and reducing auditing pressure.

Description

technical field [0001] The invention belongs to the technical field of medical detection, and relates to an automatic examination system and method for urine routine examination in a clinical laboratory. Background technique [0002] The clinical urine testing laboratory is the most basic and routine part of the laboratory department. Regardless of the size of the laboratory, it should be equipped with clinical urine testing items. The testing items it provides include urine physics, chemical testing, urine formed component testing and microscopic examination. For a long time, due to the many factors affecting the urine sample collection stage, more personnel skills and microscopic examination skills are required in the analysis, and the degree of combining clinical information after analysis is high, so although it is a basic and necessary test item, it has not been widely accepted. Good automation and standardization. Before the advent of automated urine formed component...
