Examination Details and Precautions

Blood tests

【Please be sure to read before venipuncture procedures such as blood sampling, intravenous injections or infusions】

If you have felt sick or have lost consciousness in the past due to blood sampling or infusions, please notify us so that we may safely perform the procedure. The needle may hit a thin subcutaneous nerve (peripheral nerve) during blood sampling, intravenous injection, or infusion. This can cause pain that may be more intense than usual, followed by a numbness and the pain may persist, but in most cases, the after-affect will subside in a matter of days or weeks. However, in extremely rare cases (once out of 10,000 to 100,000 cases), the pain and numbness may last long-term and the hand may suffer permanent damage. The location of the peripheral nerves varies greatly from person to person, making them imYou may take your medication as usual. to locate in advance, and modern medicine unfortunately cannot completely eliminate the risk entirely. Please be aware that by consenting to blood sampling, intravenous injections, infusions, or any other venipuncture procedures you are agreeing to incur the risks of such rare occurrences.

In the unlikely event that this happens, we will provide the best treatment we can offer. Please note that the medical treatment at that time will be eligible for insurance coverage.

【Tumor markers】

This test measures specific substances produced by tumor cells mainly in the blood (serum). However, these specific substances are also produced in normal cells thus it does not immediately indicate the presence of a tumor.

・ The PSA level may be lowered if you are on medicaion for AGA.

CT / X-ray Examinations

Upper Digestive Tract Endoscopy (Upper GI Endoscopy) Examination

【Instructions and Consent form for Upper Gastrointestinal Endoscopy】

【Please review carefully, if you are requesting to use sedation】

※Reservation is required in advance. Please call the reservation center.

Those who are diagnosed or suspected with glaucoma ( increased intraocular pressure.) or Enlarged Optic Disc Depression should consult with an ophthalmologist in advance. It must be confirmed that you may use sedatives with a written document (medical certificate etc.)or confirm by consulting or phoning an ophthalmologist.

If you use sedatives, you cannot drive, drink or exercise on the day of the exam. You will also need to rest for about an hour after the inspection.

Warfarin (warfarin K) an anticoagulant initiates smooth blood flow and is used for medication and prevention for cerebral infraction, myocardial infraction, lower limb vein thrombosis, pulmonary thromboembolism etc.

Since there is an increased risk of post-procedure bleeding , we are not able to collect tissue examples (biopsy) at our clinic even if you take the medication with a physician’s requirement.If that is the case, we will refer you to a specialized medical institution that performs it.

We ask for your understanding of the safe conduct of examinations.

List of Restricted Drugs (PDF)
Upper Digestive Tract X-ray (Barium) Test

The upper gastrointestinal tract X-ray (upper GI) test is a test in which barium (a barium sulfate preparation) is consumed. Barium is a medicine that clearly shows up in the stomach and is needed for a detailed examination. However, sometimes after drinking barium, one can experience side effects such as constipation, temporary diarrhea, anal pain, and nausea. Additionally, in rare cases, there has been reports of patients experiencing shock (allergic symptom) called barium hypersensitivity. To ensure that patients understand the necessity and dangers of the barium exam, and that examinations are safely conducted, please check the following contraindications.

Please note that in addition to contraindications, the examination may be refused or terminated if there are retained gastric contents on the day of the examination, as it interferes with imaging and reading diagnosis, and there is also a heightened risk for vomiting or aspiration.
In particular, patients taking GLP-1 or GIP/GLP-1 Receptor Agonists for diabetes or obesity treatments or weight loss purposes, even if they have abided by the fasting period, are significantly more likely to have retained gastric contents.
Furthermore, if you have an on-body device (e.g., continuous glucose monitor, insulin pump, etc.), because it may affect the operation of the device, please remove it before the examination with permission from your doctor.

After the examination, please drink plenty of water to help the barium pass through your system more quickly.

Precautions before conducting the examination

Magnetic force and radio waves do not usually affect the human body, but if there is metal on the surface or inside the body, not only does it affect the accuracy of the test, but it can also result in dangerous situations where the metal generates heat.
