All Daye tampons are manufactured at a facility compliant with medical device manufacturing standards, including ISO 13485 and GMP. Our testing kits are analysed by UKAS-accredited and CQC-registered partner laboratories. As with any diagnostic test, results should be interpreted by a qualified healthcare professional, taking into account the patient’s symptoms and medical history. Daye also offers the option to book appointments with independent, CQC-regulated healthcare providers for clinical interpretation and care. Any prescriptions or treatments offered via the Daye platform are issued by third-party, independent pharmacies regulated by the GPhC and CQC.
