For most people, medical conditions only reveal themselves once they have escalated. High-stress lifestyles and other environmental factors quietly take a toll on our health without raising any warning signals. Preventative medicine addresses this problem by conducting a comprehensive full-body checkup designed to identify silent threats and detect illnesses in their earliest, most treatable stages. Hence, by proactively monitoring health metrics, one can significantly improve one’s longevity and quality of life. A full-body checkup is just one of many procedures offered by Pyramedicine. This blog will introduce the most common tests involved in a full-body checkup, and explain how and why they work.

1. Blood tests

Blood tests are a cornerstone of any checkup. Complete Blood Count (CBC) evaluates red blood cells, white blood cells, and platelets to assess overall health and detect disorders such as anaemia or infections. A lipid profile measures cholesterol (HDL/LDL) and triglycerides to assess your long-term heart disease risk. Blood Glucose tests screen for diabetes by measuring the plasma sample’s sugar levels. Kidney function tests monitor markers like creatinine and blood urea nitrogen to check that your kidneys are effectively eliminating waste. Lastly, thyroid function tests measure hormone levels, which can reveal metabolic disorders.

2. Urine tests

Concerning renal health, urinalysis is used to detect urinary tract infections (UTIs), kidney disease, and other underlying conditions by analysing the content of the urine. Meanwhile, Microalbumin Tests specifically screen for early signs of kidney damage, which is particularly vital for patients with diabetes.

3. Imaging and Vital Screenings

Imaging allows clinicians to see what is happening inside the body without invasive procedures. Chest X-rays are used to evaluate the lungs, heart, and chest wall to identify lung disease or heart enlargement. Doctors can assess other organs like the liver, gallbladder, and pancreas for abnormalities or tumours using an abdominal ultrasound. Lastly, Blood pressure measurements are used to identify hypertension. Hypertension is commonly called the “silent killer” because it lacks obvious symptoms in most cases.

4. Cardiovascular Screenings

Heart tests determine how well your cardiovascular system handles stress and daily function. Firstly, an electrocardiogram is a non-invasive test that monitors the heart’s electrical activity to detect arrhythmias. Echocardiograms are an ultrasound of the heart which shows doctors its structure, valves and chambers. A stress test involves the patient doing physical activity like walking on a treadmill while measuring heart function to diagnose coronary artery disease.

5. Cancer Screenings

Early detection through screening is one of the most effective ways to reduce cancer mortality. Mammograms are a breast X-ray recommended for women to detect breast cancer. Pap smears and pelvic exams are used to screen for cervical cancer, among other issues related to reproductive health. The Prostate-Specific Antigen (PSA) Test is a blood test used to screen for prostate cancer risk in men. Lastly, colonoscopies, which examine the colon for polyps or cancer. Some checkups may even use AI-assisted technology to help identify smaller polyps more accurately.

To ensure the most accurate results, most doctors will recommend the following actions before the checkup.

  1. Fasting for 8-12 hours before the blood draw
  2. Abstaining from alcohol for at least 24 hours before the checkup
  3. Resting for 6-8 hours, as lack of rest can cause blood pressure and heart rate to be abnormal

However, advice will differ from case to case, and it is always best to follow your doctor’s specific instructions and communicate if you have any doubts.
