What can a urine analysis tell you?
The function of urinalysis is to provide a clear understanding of the physiological functions and pathological changes of the urinary system. It aids in the diagnosis and provides data reference for other systemic diseases such as diabetes, pancreatitis, jaundice, heavy metal poisoning, Cushing’s disease and pheochromocytoma, and can serve as a monitor for safe medication administration. It can also help diagnose whether a patient has obstetric and gynecological conditions.
The most noteworthy function of the urine analyzer is to determine whether a patient’s urinary system has hidden diseases. When a patient has a urinary tract disorder, a routine urine test can be done under the guidance of a doctor, along with other tests such as kidney function tests and blood tests, to clarify the diagnosis and help the patient recover. The doctor gets to know the patient.
How does the urine analyzer perform the test?
The essence of the urine analyzer test principle is the absorption and reflection of light. A liquid sample is added directly to multiple reagent strips that have been solidified with different reagents. The corresponding chemical composition of the urine changes the colour of the modules containing the various special reagents on the multiple reagent strips. The shade of colour is related to the specific chemical in the urine sample and is proportional to the concentration of the components; When multiple strips are placed in the colorimetric sampling tank of the urine analyzer, each module is irradiated in turn by the instrument’s light source to produce different reflected light, the instrument receives the light signals of different intensities and converts them into the corresponding electrical signals , then the microprocessor (CPU) calculates the reflectance of each test item and then compares it with the standard curve The results are then automatically printed out in a qualitative or semi-quantitative manner, allowing the patient’s physical condition to be reflected visually.
There are two types of urinalysis systems: integrated urinalysis systems and in-line urinalysis systems.
The integrated urine analysis system consists of a dry urine chemical analysis module and a urine organic fraction analysis module. The system has functions such as automatic sample feeding and automatic system cleaning,It is able to analyse urine indicators and organic fractions and give a comprehensive analysis report.
The pipeline urine analyzer system consists of two or more dry urine chemistry analyzers and a urine organic fraction analyzer. The system is connected to each urine analyzer through an automatic specimen transfer device, with automatic transfer, sample addition and automatic system cleaning, and can automatically analyse chemical indicators, scientific indicators and organic fractions in urine and give a comprehensive analysis report. Streamline urinalysis systems are faster than integrated urinalysis systems and can be modularised and flexibly docked, but require more space for placement.
Urine analyzers are generally controlled by a microcomputer and use a spherical integrator that receives dual wavelength reflected light to determine semi-quantitatively the colour change of the test strip. A pad containing several of the reagents, each reacting independently with the corresponding component of the urine and displaying a different colour, the shade of colour being proportional to some component of the urine, and other reagents colour, the change produced by the urine being compensated for by the error produced by the coloured urine on the instrument. The reagents adsorbed with urine are placed on the instrument slot and placed on the chemical reagents for reaction. Light irradiates the various reagents and the reflected light is a spherical integrator. The spherical integrator photocell reflects double wavelength light irradiation, the choice of wavelength is determined by the experimental project.The function of the urine analyzer can help the hospital or laboratory to complete most tests, and then help patients to treat more effectively.
