About Sejoy
Company identity
Sejoy is a home-use in vitro diagnostic (IVD) product manufacturer based in Yuhang, Hangzhou, China. The company states on its own website that it was established in 2002 and that it designs and manufactures home medical instruments. Its product scope covers blood glucose monitoring, lipid panel monitoring, hemoglobin monitoring, uric acid monitoring, urine analysis, women's health and fertility testing, infectious disease testing, drug-of-abuse testing and smart pen injectors.
Two name variants appear in the company's own published material and are recorded here side by side rather than resolved into one. The source-table company name is Hangzhou Sejoy Electronics & Instruments Co., Ltd. The company's website titles use Hangzhou Sejoy Electronics & Instrument Co., Ltd., with the singular Instrument. The contact page of the company's website names the entity Sejoy Biomedical Co., Ltd., and the website footer carries the same Biomedical name in its copyright line. The relationship among these three names is listed for written confirmation by the customer and is not settled on this site.
Certificates available upon request.
What the company states about its own operations
The company profile states that its products are designed by its own research and development team and manufactured to the ISO 13485 standard, and that its glucose systems comply with EN ISO 15197:2015. It also states that it has its own mould team and workshops for injection moulding, production assembly, screen and pad printing and UV curing, and that it applies 100% mass-production ageing tests, 100% material tests and 100% function tests. Those workshop and testing statements are the company's own descriptions; this site does not present workshop photographs as evidence, because the company's producing-facilities page carries no text that could be verified and no photograph on this site is labelled as a factory photograph.
The company profile states a 2020 turnover figure of 250 million US dollars. That figure is a company self-description from its history page, is repeated here only with that attribution, and is not used as a selling claim elsewhere on this site. The company profile also states that its customers are located around the world; no individual customer name is published on this site, because no customer name is evidenced in the company's own material.
Who this site serves
The buyers served are overseas distributors, importers and brand customers sourcing home-use diagnostic instruments and reagents, including customers seeking OEM and ODM supply and private-label supply. The Wholesale & OEM page sets out the order process, and the Private Label Diagnostics page describes private-label supply in general terms. Before payment, confirm availability, pricing, lead time and documentation in writing for the specific product.
Certificates are available upon request. The company's published material names standards including ISO 13485, CE, FDA, RoHS, REACH, MDSAP and Health Canada approval at name level only, without certificate numbers or issuing-body evidence, and this site follows the same name-level wording. No certificate number is stated anywhere on this site.
How the company's history is presented here
Certificates available upon request. That distinction matters for trade buyers, because a milestone such as a certification or an approval is only as strong as the documentation behind it, and documentation for any specific product should be requested in writing.
The same attribution discipline applies to the company's turnover figure and to its statements about customers around the world. Both are company self-descriptions, repeated here with attribution where they appear, and neither is used as a selling claim elsewhere on this site. No individual customer is named anywhere on this site, because no customer name is evidenced in the company's own material.
What this site will not claim
This site will not claim a factory photograph, a certificate number, a named customer, a named individual contact, or a specification for a model that has no specification table. Those absences are deliberate. The company's producing-facilities page carries no verifiable text, so no photograph here is labelled as a factory photograph. Its published material names standards at name level only, so no certificate number appears here. Its public pages name no individual contact, so none is published here. And its product posts include automatically generated title pages whose titles do not match their bodies, so only two models carry specification pages here.
Buyers who need any of those items should ask for them in writing. A factory visit, a certificate copy, a named contact for an order, or a specification for a named model are all normal requests in trade sourcing, and the inquiry form on the Contact page is the route for each of them.
