  • The PCR test is a test to determine whether or not novel coronavirus is present in the specimen collected, and even if the PCR test result is negative, it does not completely deny the presence of novel coronavirus in the body or the possibility of future infection. Even if the test result is negative, please continue to take precautions against infectious diseases.

  • If you have been tested and the test result is positive, the notification of the outbreak cannot be cancelled for any reason.

  • Once the test is done, the test fee and option fees are non-refundable for any reason. The fee-based option is an option that gives priority over the normal testing process, and no refunds will be made for delays caused by congestion at the testing center or retests.

  • If you request a negative certificate and the test result is positive, the negative certificate fee will not be issued and can be refunded. Please come to the store you used after the quarantine period is lifted.

  • Our store and our company (FOUR-LEAF Co., Ltd.) will not be responsible for or guarantee any trouble or damage caused by the validity time of the negative certificate for overseas travel or the method of specimen collection. Please be sure to check the latest information on the validity time and specimen collection method of negative certificates for each country by yourself.

  • Persons with symptoms such as fever and cough or something will not be admitted. We are a specimen collection center affiliated with a medical institution, so we cannot provide medical treatment by a doctor.

  • We reserve the right to refuse entry to those we deem to be unsuitable, such as those who do not wear masks or other minimum infection control measures, or those who have inconvenienced or may have inconvenienced other patrons.

  • Even if multiple people use the service at the same time, we cannot promise to report the results at the same time due to the congestion at the inspection site, re-testing, or other circumstances.

  • If you use the free inspection in the prefecture and your data is found to be false, you may be billed for the inspection fee by the respective prefecture. We will only conduct the inspections after you have agreed to our confirmation items, and in such cases, the issue will be between you and the respective prefecture. Our company and our stores will not be involved in any way.

  • The test results reported by our company cannot be withdrawn for any reason.

  • The PCR test performed by our company is the RT-PCR method, which is a definitive diagnosis made by a physician.

  • The test result in the test result notification does not indicate whether or not the patient is infected with COVID-19, so the test result letter cannot be treated as a document containing a physician's diagnosis. Tipically, a negative certificate must include a physician's diagnosis.

  • The expiration date on the test result notification is the period set by the Ministry of Health, Labour and Welfare, and does not deny the possibility of infection or development of COVID-19 infection within this period.

  • The negative certificate issued by our company is an official document diagnosed by a physician and can be applied to documents related to overseas travel and insurance.

  • The PCR test does not cure or alleviate symptoms.

  • The diagnosis is made by our affiliated medical institution (FIRE CLINIC), but we cannot issue prescriptions for oral medication, etc., as this is not a medical examination.
