Definition of Health Check Items

Every individual health check item has its clinical significance and the results also vary according to gender, age and medical history.  The following information and reference range of the results are for reference only and please do not interpret the report by yourself.

Instead, medical report should be explained by doctor or professional medical staff. Physical examination may also be required during report explanation for risk assessment and suggestions giving.
  • Body Mass Index (BMI)
  • Body Mass Index (BMI) is a ratio of weight to height [weight(kg)/height(m)2 to determine whether a person is at healthy weight. Obesity increases the risk of various diseases like diabetes and heart attack while underweight implies underlying illnesses or malnutrition.

    Calculation of BMI: weight(kg)/height(m)2

    BMI and Associated Disease Risk of Asian Adults:
    BMI Index (kg/m2) Category Associated Disease Risk

    Central Obesity & Waist Circumference

    Waist circumferences exceed the below standard are defined as central obesity
    Sex

    Waist Circumference

    Male

    90cm or above

    Female

    80cm or above

  • Body Fat Percentage
  • Body fat percentage is a ratio of body fat to weight. The healthy range of body fat percentage for male and female should be 10%-20% and 15%-25% respectively. Body fat percentage over 25% (for male) and 30% (for female) imply overweight which will increase the risk of various diseases like diabetes and heart attack.

  • Blood Pressure
  • Blood pressure means the pressure pushing against the arterial walls when blood is pumped into arteries.  There are two numbers in the blood pressure, namely “Systolic pressure” (upper pressure) and “Diastolic pressure” (lower pressure).

    Persistent high blood pressure poses serious risk to health by increasing the likelihood of stroke, coronary heart disease or chronic kidney disease, etc.  On the contrary, persistent hypotension may cause headache, dizziness and chest tightness, etc. 

    Reference Range of Blood Pressure

    Category Systolic (upper pressure)
    mmHg
    Diastolic (lower pressure)
    mmHg

    Hypertension

    > 140

    > 90

    Moderate High

    120 – 139

    80 – 89

    Normal

    < 119

    < 79

    Hypotension

    < 90

    < 50

  • Complete Blood Count (CBC)
  • CBC is a routine blood analysis for screening of anaemia, infection or other haematological diseases.

  • Blood Glucose (Fasting)
  • Blood Glucose (Fasting) measures the glucose level after fasting for at least 8 hours (no food or drink except water).  It is a commonly used test to diagnose diabetes. 

    Reference Range of Blood Glucose Level

     

    Normal

    Marginal

    High

    Fasting

    < 6.0mmol/L

    6.0-7.0mmol/L

    ≥ 7.1mmol/L or above

    After meal

    < 6.0mmol/L

    6.0-11.0/mmol/L

    ≥ 11.1mmol/L or above

  • Total Cholesterol
  • Cholesterol is a fat-like substance that is a part of cell membranes.  Total Cholesterol is the total level of cholesterol in the blood.  High cholesterol levels may cause hypertension or cardiovascular disease while low cholesterol levels imply malnutrition, weaken of immune system or anaemia, etc.

    Reference Range of Total Cholesterol Level

     

    Total Cholesterol Level

    Desirable

     5.16mmol/L

    Borderline

     5.16-6.17 mmol/L

    High Risk

    >6.18 mmol/L

  • HDL Cholesterol (HDL)
  • HDL is known as “good cholesterol” and it helps to clear the LDL from the bloodstream in order to prevent heart attack and stroke.

    Reference Range of HDL

     

    Normal Level

    Adult Male

    > 1.0 mmol/L

    Adult Female

    > 1.3 mmol/L

  • LDL Cholesterol (LDL)
  • LDL, known as “bad cholesterol”, is relatively rich and easily create blockage in blood vessels.  Therefore, the LDL level should maintain low to reduce the risk of cardiovascular disease. 

    Reference Range of LDL

    LDL Level

    Optimal

    < 2.6 mmol/L

    Near Optimal

    2.6 – 3.3 mmol/L

    Borderline High

    3.4 – 4.1 mmol/L

    High Risk

    4.2 – 4.9 mmol/L

    Very High Risk

    > 4.9 mmol/L

  • Triglycerides
  • Triglyceride is synthesized by glycerol and fatty acid.  High triglyceride levels mean greater risk of heart disease and diabetes.

    Reference Range of Triglycerides

     

    Level of Triglycerides

    Desirable

    < 1.7 mmol/L

    Borderline

    1.7 – 2.2 mmol/L

    High Risk

    2.3 – 5.6 mmol/L

    Very High Risk

    > 5.6_mmol/L

  • Renal Function (Creatinine)
  • Creatinine is produced from creatine, a molecule of major importance for energy production in muscles.  The creatinine is filtered out of the blood by kidneys and then passed out of the body in urine.  It is commonly used to detect renal failure and increase/decrease of creatinine amount in the blood may imply that the kidneys are not function normally. 

    Reference Range of Creatinine

    Normal Level

    Adult Male

    80 – 115 mmol/L

    Adult Female

    53 -97 mmol/L

  • Liver Function (ALT/SGPT)
  • ALT/SGPT helps to check liver damage and to identify liver disease like hepatitis, cirrhosis or fatty liver, etc. 

    Reference Range of ALT/SGPT

    Normal Level

    Adult Male

    < 45 IU/L

    Adult Female

    < 34 IU/L

  • Uric Acid
  • Uric acid test helps to assess the possibility of gout. However, the uric acid level may vary due to alcohol/purine intake, caused by other diseases (e.g. diabetes, renal failure, thyroid) or pregnancy.  Therefore, physical examination by doctor is required to diagnose for gout. 

    Reference Range of Uric Acid

    Normal Level

    Adult Male

    0.19-0.43 mmol/L

    Adult Female

    0.14-0.37 mmol/L

  • Stool for Occult Blood
  • The stool for occult blood test checks for hidden (occult) blood in the stool. Possible causes of occult blood in stool include colon cancer, colonic polyps or symptoms of other diseases.  Follow up examination is required if test result is positive.

  • Resting ECG
  • Resting ECG is commonly used for preliminary cardiac diseases assessment.  Client is required to lie on a bed during the ECG for detection of heart diseases like arrhythmia, ischemic heart disease, etc. 

  • Chest X-ray
  • Chest x-ray is the common imaging test which assists in finding problems inside the chest like tumors, pulmonary tuberculosis, airway diseases, cardiac enlargement or scoliosis, etc.

  • Cervical Smear 
  • Cervical smear is a simple test to detect abnormal cell changes in the cervix.  If abnormal cells are detected, further tests are needed.  Women who have ever had sexual experience are recommended to have regular cervical smears.
