Biomarkers are substances that can be measured objectively and analyzed to determine whether a patient's kidney function is normal or abnormal. Biomarkers can also evaluate pathogenic processes or pharmacological responses to therapeutic interventions. Therefore, they are essential to the identification and prognosis of acute kidney injury (AKI) and chronic kidney disease (CKD).

Biomarkers can be cells found on a urinalysis, proteins, microRNAs, genes, lipids, metabolites, or proteomic patterns. In the case of CKD, in particular, biomarkers are typically those that can be used to assess the kidney's glomerular filtration rate (GFR). This decline denotes a decline in renal function. GFR measurement is essential for CKD diagnosis, illness monitoring, and drug dosage determination. The main indicators to calculate GFR include blood urea nitrogen (BUN), urine albumin/protein, serum creatinine (SCr), and volume excretion.

Segmental Analysis

Based on biomarker type, the global renal biomarkers market is bifurcated into functional biomarkers, up-regulated proteins, and other biomarker types. 

The functional biomarker segment dominates the global market and is anticipated to grow at a CAGR of 7.35% over the forecast period. The functional biomarker segments are further sub-segmented into serum creatinine, serum cystatin C, and urine albumin. Serum creatinine is the most widely used laboratory test for kidney function and is used to derive the eGFR (estimated Glomerular Filtration Rate) as an indicator of kidney function. It is also used as an ideal indicator for determination of chronic kidney diseases. In addition, Cystatin is a protein produced in the body by the cells. Cystatin C concentration in the blood is entirely dependent on kidney function. Albumin is synthesized in the parenchymal cells of the body. The blood plasma, cerebrospinal fluid (CSF), and urine have around 50% albumin in the body. The urine albumin segment is driven by the availability of these biomarkers through major companies across the market.

The up-regulated protein segment is further sub-segmented into neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, and interleukin 18. NGAL (Neutrophil Gelatinase Associated Lipocalin) is a novel biomarker to diagnose acute renal injury (AKI) early. Kidney injury molecule-1 (T-cell immunoglobulin; mucin-containing molecule) is a type 1 transmembrane protein. KIM-1 is up-regulated in the kidney's dedifferentiated proximal tubule epithelial cells after ischemic or toxic injury. Interleukin 18 (IL-18) is an 18kDa novel cytokine identified as a co-stimulatory factor for producing interferon-γ (IFN- γ) in response to toxic shock. The precursor 24kDa molecule of IL-18, which lacks a signal peptide and needs to be broken down to form an active molecule, is produced during IL-18 synthesis.

Based on diagnostic technique, the global renal biomarkers market is bifurcated into enzyme-linked immunosorbent assay, colorimetric assay, particle-enhanced turbidimetric immunoassay (PETIA), chemiluminescent enzyme immunoassay (CLIA), and liquid chromatography-mass spectrometry (LS-MS).

The enzyme-linked immunosorbent assay segment owns the highest market share and is predicted to exhibit a CAGR of 7.19% over the forecast period. ELISA tests can be done quickly and are easy to carry out since they are designed to handle many samples in parallel rapidly. They represent a very popular choice for evaluating various research and diagnostic targets. The diagnostic kit DNlite-IVD103 has received the CE IVD mark and is authorized for sale in the European Union, according to a July 2020 announcement from Taiwan's Bio Preventive Medicine Corporation (BPM), a cutting-edge in-vitro diagnostic (IVD) firm. The "DNlite-IVD103" diagnostic test for stopping the progression of diabetic kidney disease is the first ELISA (Enzyme-linked Immunosorbent Assay) diagnostic kit to be made available globally.

Measuring a compound's concentration in a solution using a coloring agent is known as a colorimetric test. The colorimetric assay method is widely used in diagnostic laboratories and hospitals to diagnose different diseases. Due to their wide availability, there is a rapid growth in the number of improved colorimetric assay techniques for measuring protein concentrations to detect kidney diseases.

Based on end-user, the global renal biomarkers market is divided into hospitals, diagnostic laboratories, and others. 

The diagnostic laboratories segment is the most significant contributor to the market and is anticipated to exhibit a CAGR of 8.21% over the forecast period.
