An unexciting market

Urinalysis not directly needed for COVID-19 testing is attempting to find relevance.

Urinalysis instruments and reagents not being needed for detecting the coronavirus, unlike their counterpart, the molecular diagnostics, the segment was drastically hurt ever since the virus reared its ugly head, and raged havoc across the world. However, the values of urinary disorders such as urinary tract infections, kidney disease, and diabetes vary when comparing urine samples of normal patients with those of COVID-19 patients. This mainly happens as the coronavirus affects the kidney organ.

According to a study published in Clinical Chemistry and Laboratory Medicine Journal, the urine sediment analysis revealed the presence of erythrocytes and casts in nearly half of the patients; and a sediment analysis of COVID-19 urine samples detected the presence of myoglobin casts or cellular debris casts, diffused erythrocyte aggregation, and obstruction in the lumen of glomerular, peritubular capillaries without platelets, red blood cell fragments, fibrin thrombi, or fibrinoid necrosis. A urinary sediment analysis study also in acute kidney injury associated with COVID-19 revealed a fair abundance of coarse granular casts and muddy brown granular casts in 75 percent of the cases, whereas half of the specimens revealed the presence of waxy casts, and a smaller fraction contained renal tubular epithelial cell casts.

Similar other studies made urinalysis analysis relevant at these times when other routine tests were at absymal low levels.
Urinalysis has always been a major diagnostic screening test in diagnosing and monitoring nephrological and urological conditions. Until recently, microscopic urine sediment analysis was the most widely accepted urinalysis methodology. However, this time-consuming methodology is associated with extensive analytical errors. Over the past 25 years, new automated technologies and informatics have greatly reduced the labor intensity of urinalysis and have created new technical possibilities.

New technological advances have paved the way for significant progress in automated urinalysis. Quantitative reading of urinary test strips using reflectometry has become possible, while complementary metal oxide semiconductor (CMOS) technology has enhanced analytical sensitivity and shown promise in microalbuminuria testing.

Microscopy-based urine particle analysis has greatly progressed over the past decades, enabling high throughput in clinical laboratories. Urinary flow cytometry is an alternative for automated microscopy, and more thorough analysis of flow cytometric data has enabled rapid differentiation of urinary microorganisms. Integration of dilution parameters in urine test strip readers and urine particle flow cytometers enables correction for urinary dilution, which improves result interpretation. Automated urinalysis can be used for urinary tract screening and for diagnosing and monitoring a broad variety of nephrological and urological conditions; newer applications show promising results for early detection of urothelial cancer.

The introduction of matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) has enabled fast identification of urinary pathogens. Automation and workflow simplification have led to mechanical integration of test strip readers and particle analysis in urinalysis.

As the information obtained by urinalysis is complex, the introduction of expert systems may further reduce analytical errors and improve the quality of sediment and test strip analysis. With the introduction of laboratory-on-a-chip approaches and the use of microfluidics, new affordable applications for quantitative urinalysis and readout on cell phones may become available.

The Indian market for urinalysis analyzers and reagents in 2020 is estimated at ₹145 crore. Reagents continue to dominate with an 80-percent share, valued at ₹145 crore. The market took a major hit in 2020, and continues to be on lower levels than 2019, since urinalysis has minimal role to play in COVID-19 testing or treatment.

The fully automated analyzers segment is estimated at ₹13.05 crore in 2020. In the semi-automated instruments category, amounting to ₹15.95 crore, the entry level instruments are marginally higher contributing 54 percent to the segment, by value.

One of most popular routine health-screening tests, 2020 has not been a great year for this segment. Molecular diagnostics, the mainstay for COVID-19 testing is completely different. A team in India comprising Supraja Sundaram, Mamta Soni, and Rajeev Annigeri have put forth their study that urine abnormalities predict acute kidney injury in COVID-19 patients. Their results suggest that urine analysis is a simple test, which can be used to predict development of AKI and mortality and may be used for risk stratification of COVID-19 patients, especially in low resource settings. With the opening of the lockdown, 2021 seems more promising, although not expected to reach 2019 levels.

It also plays an important role in the evaluation of liver function and several urological malignancies. In addition to detecting leukocytes and nitrites, a urine microscopy identifies bacteria. These findings are crucial to the treatment process. In the current pandemic, urinalysis is a useful in unveiling potential renal impairment due to COVID-19.

Technological advancements
Adoption of automation in sediment analysis has paved the way for significant progress in urinalysis. These systems reduce human intervention, making it possible to standardize results, and streamline workflow and increase laboratory productivity.

AI based element identification systems. Integration of AI with digital bright-field microscopy in automated sediment analyzers provides clear, high quality images mimicking visual microscopy. These systems are enabled to recognize thousands of known sediment elements. This considerably reduces repetitions, while improving accuracy and reliability of sediment particle detection and differentiation. Additionally, when an atypical cell appears on the screen, the pathologist can check the accuracy of the automatic identification and further evaluate to confirm the sub-types.

Expert systems reduce analytical errors in sediment and test strip analysis.

Integrated operating mode. Fully automated analyzers integrate analysis of chemical parameters on test strips and urine sediment examination in a format compatible with manual microscopy.

Gravity sedimentation. Compared to centrifugation, gravity sedimentation ensures less damage to fragile elements like casts, and a lower risk of RBC lysis. This result in cost savings as it allows re-use of cuvettes.

Active humidity protection of diagnostic strips. Dessicators and silica gel bags, aid in maintaining humidity up to 40 percent lower than ambient humidity, eliminating false positive results.

Among other benefits, these technological advancements lead to decreased usage of consumables, resulting in cost-effective operations.

Urine analysis comprises of physical, routine, and microscopic examination. It is an integral part of clinical laboratories and one of the most performed diagnostic tests. This simple, noninvasive test is potent screening tool for clinicians, which can provide as much as possible information on the status of renal, urological, infection, and metabolic function in the body. Apart from routine screening, it may also be helpful in uncovering status of disease that may not be showing significant signs or symptoms.

A lot of vital information can be obtained through urine examination, still its clinical utility is affected to a great extent by limitation of its conventional manual methods including bio-chemical and microscopy. Biochemical analysis is improved with reagent strips, but challenge remained in microscopic part. Other challenges like non standardization of process, person to person variation, centrifugation, and slide preparation needed a whole automated system in place with minimum human involvement and maximized automation.

In last decade there were paradigm shifts in laboratory operations and now automation is leading the way for urinalysis testing. Technological advancement in biochemical analysis and microscopic examination in urinalysis have helped to set and standardize process. Automation has changed the way of testing, reporting and documentation of laboratories with improved quality and lowered TAT. Some of the key features of automation in urinalysis are standardization, quality control, added clinical values, data management, accuracy, and reproducibility.

Automation in urinalysis can be further categorized in bio-chemical analysis and particle analysis (microscopy). In bio-chemical analysis, the CMOS sensor has played a great role in identifying strip pad position, optimizing detection area, correction of abnormal coloration. This cutting-edge technology has eliminated all possible errors due to manual process. Similarly, for particle analysis, fluorescence flow cytometry technology has great advantage as it can recognize specific and unique properties of different particles by size, labeling DNA, complexity, and specific features, and so determining the particle type. Also, high accuracy of bacteria counts and, accurate differentiation in RBC morphology (Isomorphic and Dysmorphic) are helping in faster diagnosis and better patient care. Looking at the facts, it can be concluded that future of urinalysis lies in automation.

Although dry-chemistry technology for urinary test strips has made limited progress, advances in electronic detection have considerably improved. An interesting recent evolution is the use of smartphones for reading and interpreting urine test strip results. According to the reflectance theory, the reciprocal value of reflectance readings is proportional to the concentration of the measured analyte.

In manual microscopy, several steps, such as centrifugation, decantation, and re-suspension, led to cellular lysis and loss. Progress in informatics and computer technology has enabled the development of automated microscopy based on pattern recognition.

Urine particle flow cytometers (UFCs) have improved count precision and accuracy, compared with visual microscopy and offer significant labor reduction. Clinical studies using UFCs have focused on diagnosis and monitoring of urinary tract infection; localization of the sites of hematuria; and diagnosis, monitoring, and exclusion of renal disease. Depolarized side-scattered light was introduced to improve crystal sensitivity and to better discriminate between RBCs and crystals; however, in contrast to microscopy-based readers, differentiation of crystals is not possible. A popular approach is combining test strips with UFCs for screening purposes either using both strips and UFC or by utilizing the urine strips for parameters unrelated to the UFC-analysed particles. As mechanical coupling of UFCs and test strip readers has been introduced, expert systems now take advantage of the combined information and apply user – definable decision criteria. This implementation significantly reduces microscopy review rates and saves time and labor cost.

In view of the great demand for the development of cost-effective portable readers, pocket-sized urine strip readers can be combined with dipsticks in a device that is capable to send digital information using a smartphone, offering a solution for detecting urological or nephrological diseases in regions with limited availability of experts. Advances in microfluidics have enabled the development of chip-based assays, which might change urinalysis in the years to come. Alongside conventional urinalysis applications integrated microfluidic chips show promise for the quantitative detection of bladder cancer cells in urine. Similarly, microfluidic paper devices have been described for detecting bacteria causing UTIs and sexually transmitted diseases in urine specimens.

Over the past 20 years, automated urinalysis has undergone a technical evolution. In this respect, automated test strip reading provides added value. Further integration of existing technologies may contribute to reduce turn-around times. Consolidation of clinical laboratories has also led to a reduction of their number and has increased the distance between patient and laboratory; this trend creates a major pre-analytical challenge. Despite improvements in standardization, most of errors in urinalysis occur outside of the analytical phase; pre-analytical steps, in particular, are much more vulnerable. As analytical variation has been greatly reduced, more efforts need to be focused on the pre-analytical phase.
