Interpretation of Medical Examination Results in Japan: 5 Key Rules
Interpretation of medical examination results in Japan is a crucial step that determines the accuracy of diagnosis and the effectiveness of further treatment. In this guide, we will explain in detail how to correctly read Japanese doctors’ conclusions, understand reference values, and diagnostic categories.
Professional interpretation of medical examination results in Japan — the key to accurate diagnosis and proper treatment
1. Why is correct interpretation of medical examination results in Japan important?
Medical examination in Japan is highly accurate, but without proper interpretation of results, even the most modern tests lose their meaning. In this section, we explain how to correctly read Japanese doctors’ conclusions and understand the meaning of each indicator.Key principles of interpretation
• Reference values are not absolute: “Normal” varies depending on the laboratory, equipment, and even time of day. • Comprehensive approach: No single indicator is considered in isolation. Analysis of all data together is important. • Dynamics are more important than a single value: Changes in indicators over time are often more informative than a one‑time result. • Cultural features: In Japan, specific diagnostic criteria and approaches are used that differ from Western ones. Learn more about the features of Japanese medicine in the article on medical tourism in Japan.

II. Main types of examinations and their interpretation
1. Interpretation of laboratory blood test results
This is the basis of any medical examination in Japan. Correct interpretation of results of biochemical tests allows assessment of the state of all body systems. For a comprehensive examination, we recommend learning about the Ningen Dock programme — the Japanese standard for complete medical check‑ups.Key blood indicators and their interpretation
| Parameter | Reference range | What deviation means |
|---|---|---|
| Haemoglobin (Hb) | M: 13.5-17.5 g/dL F: 12.0-15.5 g/dL | Low — anaemia, high — dehydration or polycythaemia |
| Fasting glucose | 70-109 mg/dL | Above 126 mg/dL — possible diabetes, requires consultation |
| HbA1c (glycated haemoglobin) | 4.6-5.9% | Shows average blood sugar over 3 months |
| Total cholesterol | 130-219 mg/dL | Above 240 mg/dL — increased risk of atherosclerosis |
| HDL (“good” cholesterol) | ≥40 mg/dL | The higher the better. Protects blood vessels |
2. Tumour markers: correct interpretation of results
In medical examination in Japan, tumour markers are used for screening, but their interpretation of results requires caution. If deviations are detected, specialised treatment may be required, such as prostate cancer treatment in Japan.Main tumour markers
| Marker | Normal range | What elevation indicates |
|---|---|---|
| PSA (prostate) | 0-4 ng/mL | May indicate prostatitis, adenoma, or prostate cancer |
| CA19-9 (pancreas) | 0-37 U/mL | Elevation in pancreatitis or gastrointestinal tumours |
| AFP (liver) | 0-10 IU/mL | Marker for hepatocellular carcinoma |
| CEA (GI tract) | 0-5 ng/mL | Non‑specific marker, elevated in many conditions |
3. Instrumental diagnostics: interpretation of imaging results
Modern imaging methods require special preparation for correct interpretation of results.| Method | What it shows | Interpretation features in Japan |
|---|---|---|
| Abdominal ultrasound | Liver, gallbladder, pancreas, kidneys | Japanese doctors pay special attention to early signs of fatty hepatosis |
| Chest CT | Lungs, heart, mediastinum | High sensitivity to small pulmonary nodules (early cancer) |
| PET-CT | Metabolically active lesions | Uses specific Japanese protocols, requires expert evaluation |
| Brain MRI | Brain structures, blood vessels | Special attention to micro‑strokes and early vascular changes |
III. Japanese diagnostic category system in interpretation of results
After a medical examination in Japan, you will receive a report with letter categories. Proper interpretation of results begins with understanding this system.Category system A‑E
| Category | Meaning | What to do |
|---|---|---|
| A | No anomalies found | Continue preventive check‑ups once every 1‑2 years |
| B | Minor changes | Lifestyle correction, control in 1 year |
| C12 | Follow‑up required | Repeat examination in 12 months |
| C6 | Active monitoring | Repeat test in 6 months |
| C3 | Close monitoring | Repeat in 3 months, possible specialist consultation |
| D | Treatment required | Immediate doctor consultation, additional examinations |
| E | Already receiving treatment | Continue therapy under medical supervision |

IV. Practical tips for interpreting medical examination results
What to do with your examination results
1. Don’t panic over deviations: Many indicators can temporarily change due to stress, diet, or physical activity. 2. Pay attention to dynamics: If you have results from previous years, compare them. Stable minor deviations are often less worrying than sharp changes. 3. Consider the context: Age, gender, presence of chronic diseases — all affect interpretation. 4. Ask questions: If something is unclear in the report, do not hesitate to ask. Japanese doctors usually explain results in detail. 5. Get a second opinion: Especially if the results raise doubts or if the recommendations seem unreasonable. Remember: Japanese reference values may differ from Russian or European ones. Always consider this when interpreting results.Useful resources for interpreting results
