Q Check

What Q Check does

Q Check (큐체크) is a Seoul-based direct-to-consumer health testing company founded in 2017 that sells at-home biological test kits to South Korean consumers with extension into international shipping. The company markets through its own e-commerce site (qcheck.co.kr), a physical retail presence in Hyundai Department Store, and KakaoTalk-based customer engagement, and is led by Representative Director Park Sung-hee (박성희). The product line centers on laboratory-analyzed biological samples rather than diagnostics, positioned for consumer wellness use.

Core offerings include food sensitivity/allergy panels built on IgG methodology — a 90-item panel customized for Korean dietary patterns and a broader 970-item comprehensive panel — plus gut microbiome analysis that includes profiling of obesity-associated bacterial populations, and genetic testing in 13-item and 69-item configurations. The company has extended horizontally into adjacent categories, notably a 380-item pet health testing panel and a Denplus-branded oral care line, and vertically into bundled multi-person packages (the Signature family tier) priced at a premium to single-test SKUs. The testing methodology relies on standard consumer-biological-sample workflows (collection kits shipped to consumers, samples returned for laboratory analysis, results returned digitally).

Q Check's revenue model is transactional rather than subscription-based, with single-test pricing spanning approximately ₩19,000 at the entry level up to ₩759,000 for premium Signature family bundles. Distribution combines direct digital sales, a physical retail footprint via Hyundai Department Store, and shipping to international addresses. The company has not disclosed external funding rounds and appears bootstrapped, with no public revenue, headcount, or scale metrics available in the input.

The company also sells bundled multi-person family packages, dedicated pet allergy and gut microbiome test kits, and a Dentplus-branded oral care line.
