What Litholink Corp does

Litholink Corp is a clinical diagnostics subsidiary of Laboratory Corporation of America Holdings (Labcorp, NYSE: LH), headquartered in Chicago, Illinois, and operating as a specialty reference laboratory for kidney stone prevention. The company performs 24-hour urine metabolic analysis to identify risk factors for recurrent kidney stone formation, issuing laboratory result reports with personalized prevention recommendations. Its core product is the 24-hour urine test, supported by an at-home collection kit that patients use to gather specimens over a 24-hour period, including a specialized protocol for cystine stone formers. Specimens are processed through Labcorp's national laboratory infrastructure under CAP and CLIA accreditation.

Litholink's testing service is initiated via electronic orders from healthcare providers (primarily urologists) through EMR systems or the Labcorp Link provider platform; patients without a valid Test Request Form must obtain one before a kit will be processed. Supporting services include test requisition management, collection supplies and instructional videos (English and Spanish), result delivery through the Labcorp patient portal, and billing administration that routes claims to insurance.

The business operates on a transactional laboratory testing fee model, charging per test with coverage typically through health insurance. Go-to-market is sales-led, leveraging Labcorp's provider-facing platforms, patient portal, and educational content (for example, a Kidney Stone Prevention ROI resource) to drive order volume among urology prescribers and to support institutional buyers such as managed care organizations and health systems. The unit is small (1–10 employees in firmographic data) and functions as a specialty overlay on the parent's national lab, billing, and logistics infrastructure.

Broad incumbents

• Quest Diagnostics: Quest Diagnostics is one of the two largest US clinical laboratory networks and a direct broad incumbent to Litholink's parent Labcorp. It offers comparable urine and metabolic testing panels and competes for the same urology/nephrology provider relationships.
• Laboratory Corporation of America Holdings (Labcorp): Labcorp is Litholink's parent and the broader laboratory organization within which Litholink operates. As an incumbent, Labcorp competes across all clinical lab categories including urinalysis, making it the closest structural comparable for Litholink's service model.
• Sonic Healthcare USA: Sonic Healthcare USA is a national clinical laboratory network offering routine and specialty urine diagnostics. It is a broad incumbent comparable to Labcorp in scale and competes for nephrology and urology provider accounts.

Direct peers

• ARUP Laboratories: ARUP is a specialty reference laboratory affiliated with the University of Utah that provides advanced urine and metabolic testing, including stone-risk panels. It is a direct competitor for complex urology and nephrology send-out testing.
• Mayo Clinic Laboratories: Mayo Clinic Laboratories is a major specialty reference lab offering metabolic and kidney stone-related urine testing. It competes with Litholink for specialist send-out volume, especially for complex or rare stone-former cases.
• BioReference Laboratories: BioReference (an OPKO Health company) is a full-service clinical laboratory offering urine chemistry and metabolic panels. It serves similar urology/nephrology provider customers and competes for specialized metabolic testing volume.

Emerging players

• NMS Labs: NMS Labs is a specialty reference laboratory focused on esoteric and clinical toxicology testing. While not a direct kidney-stone lab, it represents the broader specialty reference-lab category Litholink operates in for niche send-out testing.
• Eurofins Viracor: Eurofins Viracor is a specialty diagnostics lab offering esoteric testing including renal and metabolic panels. It is an emerging specialty player with overlapping clinical niches relevant to Litholink's kidney stone metabolic testing.

Others

• Boston Heart Diagnostics: Boston Heart Diagnostics (now part of Eurofins) provides specialized cardiovascular and metabolic testing. It is adjacent to Litholink in metabolic lab diagnostics for chronic disease, sharing the same provider-channel model.

Regional players

• Walk-In Lab: Walk-In Lab is a direct-to-consumer online lab-ordering platform that enables patients to bypass traditional provider orders for metabolic and urine panels. It represents the alternative consumer-facing model that could pressure Litholink's provider-gated approach.
