During an annual physical examination, blood tests are performed routinely to evaluate a person’s general health and detect possible medical conditions. These analyzes provide valuable information on the functioning of various body organs and systems, which helps doctors to make precise diagnoses and develop adequate treatment plans. Blood analysis is usually done by extracting a small amount of blood from a vein, which is then analyzed in search of specific markers or levels of different substances.

One of the most frequent blood tests that are performed during an annual medical examination is the complete hemogram, which provides important information about the number and types of blood cells of the body. This test includes red blood cell measurements, white blood cells and platelets. Hemogram can help identify diseases such as anemia, infections and blood clotting disorders.

Important Information:

  • A complete hemogram (CBC) is a common blood test that is performed during an annual physical exam.
  • The hemogram provides information about red blood cells, white blood cells and platelets.
  • It can help identify conditions such as anemia, infections and blood coagulation disorders.

Another blood test that is usually included in the annual physical exam is a complete metabolic panel (CMP). This test evaluates various substances in the blood, such as glucose, electrolytes and renal and liver enzymes. The results of a PCM can reveal important information about the blood sugar level of a person, renal function, liver function and electrolytic balance. Anomalies in these areas may indicate conditions such as diabetes, kidney disease or liver dysfunction.

Annual blood tests provide a complete evaluation of their health, which allows health professionals to detect and control possible medical conditions at an early stage. When regularly controlling their blood, health professionals can intervene promptly, initiate adequate treatment plans and help you maintain an optimal state of health.

Key Blood Tests to Include in Your Annual Physical Exam

1. Complete Blood Count (CBC)

The complete blood count is an exhaustive blood analysis that measures different blood components, such as red blood cells, white blood cells and platelets. This test provides information about your general state of health and helps identify diseases such as anemia, infections and hemorrhagic disorders. The hemogram can also reveal signs of inflammation or underlying diseases.

2. Lipid Panel

The lipidogram measures the levels of cholesterol and triglycerides, which are fat present in the blood. High levels of cholesterol and triglycerides can increase the risk of heart disease and stroke. This blood test evaluates its lipid profile, including total cholesterol levels, LDL (bad) cholesterol, HDL cholesterol (good) and triglycerides. The periodic monitoring of your lipid profile can help your doctor determine if you need modifications in your lifestyle or medication to control your cardiovascular health.

Important: Annual physical exams usually include additional blood tests depending on their age, sex, medical history and risk factors. Your doctor will determine what specific tests are necessary to evaluate your general health status and identify possible health problems.

How Blood Tests Help Identify Health Conditions Early

One of the main advantages of blood analysis is its ability to detect anomalies and imbalances in the body. With the help of these analyzes, doctors can identify deviations from normal ranges and point out possible underlying causes. For example, a complete hemogram helps evaluate the general health of a person by measuring the concentration of red blood cells, white blood cells and platelets. Any significant deviation of normal values may indicate the existence of anemia, infection or even leukemia.

I knew it?

Blood analyzes are usually included in annual physical exams to provide a complete vision of a person’s health and help in the early detection of diseases.

  • Cholesterol levels: A blood profile analysis measures the levels of different types of blood cholesterol. High levels of LDL cholesterol (low density lipoproteins) can increase the risk of heart disease, while low levels of HDL cholesterol (high density lipoproteins) may also indicate possible health problems.
  • Glucose levels: A blood test to measure glucose helps diagnose and control diabetes. High blood glucose levels (hyperglycemia) can indicate diabetes or glucose intolerance, which underlines the importance of early intervention and modifying lifestyle.
  1. Thyroid function: Blood analysis can measure thyroid stimulating hormone (TSH) and thyroid hormones (T3 and T4) to evaluate thyroid function. Abnormal results may indicate a hearing or hyperactive thyroid, which allows diseases such as hypothyroidism or hyperthyroidism.
  2. Hepatic and renal function: the tests of liver and renal function help evaluate the health and functioning of these vital organs. High liver enzymes or abnormal renal function markers may indicate a liver or renal disease, allowing to intervene early and prevent major damage.

Blood analyzes are an essential tool of preventive health care, since they allow to detect healthy health problems. Periodic blood tests, especially as part of an annual physical examination, help people and health professionals control changes in the body, identify possible risks and take proactive measures to maintain general health and wel l-being.

The Importance of Regularly Monitoring Cholesterol Levels

The main reason to regularly control cholesterol levels is to detect and manage in time the possible health risks. By measuring the levels of the different types of cholesterol and triglycerides in blood, health professionals can evaluate a person’s lipid profile, which is crucial to determine their risk of cardiovascular disease. The lipid profile usually includes total cholesterol measurements, low density lipoproteins (LDL), high density lipoproteins (HDL) and triglycerides.

The high levels of LDL cholesterol, often called “bad” cholesterol, are associated with an increased risk of developing plates in the arteries, which can cause heart disease and stroke.

Periodic control of cholesterol levels also helps evaluate the effectiveness of changes in lifestyle and medicines to control cholesterol levels. For people with high cholesterol levels, diet modifications, increased physical activity and possible medication to reduce cholesterol are common approaches to reduce the risk of cardiovascular events. The monitoring of cholesterol levels over time can help determine the success of these interventions and guide the treatment plan settings.

  1. Periodic blood tests are essential for people with a family history of hypercholesterolemia, obesity, diabetes or heart disease.

  2. People over 40 should consider the possibility of periodically controlling their cholesterol levels, since the risk of cardiovascular diseases tends to increase with age.

  3. The people to whom high cholesterol has already been diagnosed must undergo frequent monitoring tests to control their evolution and make the necessary adjustments in their treatment plan.

Sticks for cholesterol levels
Type of cholesterol Desirable level
Total cholesterol Less than 200 mg/dl
LDL cholesterol Less than 100 mg/dl
HDL cholesterol 60 mg/dl or higher
Triglycerides Less than 150 mg/dl

How Blood Tests Help Assess Liver and Kidney Function

Liver function tests:

  • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST): These enzymes are released in the bloodstream when the liver is damaged or inflamed. High levels of ALT and AST can indicate liver disease or injury.
  • Alkaline phosphatase (ALP): ALP levels help evaluate the health of the liver and bones. High levels could indicate a liver disease or an obstruction of the bile duct.
  • Bilirubin: This waste product occurs when the liver breaks down the old red blood cells. High levels of bilirubin can suggest liver dysfunction or biliary flow obstruction.

Renal function tests:

  • Urea and Creatinine: These waste products are filtered by the kidneys. Abnormal levels may indicate a deterioration of renal function.
  • Glomerular filtration rate (TFG): TFG calculates the kidneys to filter blood residues. A low TFG may indicate damage or kidney disease.
  • Electrolytes: Blood analysis measure electrolyte levels such as sodium, potassium and chloride, which are important to maintain adequate renal function and the general balance of the organism.

Periodic blood tests help health professionals identify possible liver and renal problems at an early stage, allowing to intervene and treat in time. Understanding the importance of these blood markers helps to manage and prevent liver and renal diseases better.

Discovering Potential Nutritional Deficiencies through Blood Tests

The exhaustive nature of blood tests allows health professionals to analyze different markers that indicate the levels of various nutrients in the body. Blood samples are collected and analyzed in the laboratory to measure specific parameters, such as vitamin and mineral levels, as well as other indicators of nutritional status. Some important nutrients that can be evaluated by blood analysis are iron, vitamin D, vitamin B12, magnesium and calcium, among others.

Iron: One of the most common deficiencies worldwide, low iron levels can cause anemia, fatigue and deterioration of cognitive function. Blood analysis can measure ferritin levels, responsible for iron storage in the body, and hemoglobin, which transports oxygen in red blood cells.

Vitamin D: This crucial vitamin intervenes in bone health, immune function and in various diseases. Blood analysis can evaluate 25-hydroxivitamin D levels, the main form of vitamin D that is found in the blood.

Vitamin B12: The lack of vitamin B12 can cause anemia, fatigue and nerve damage. Blood analysis can measure the levels of this vitamin in the blood and help identify deficiencies.

  • Calcium: Blood analysis can determine calcium levels, which is essential for bone health, muscle function and correct nerve signage.
  • Magnesium: This mineral intervenes in various biochemical processes of the organism. Blood analysis can evaluate magnesium levels and detect deficiencies.

By conducting blood analysis and the analysis of the results, health professionals can detect possible nutritional deficiencies and develop adequate treatment plans to correct them. Nutritional deficiencies, once detected, can be treated through changes in the diet, supplements or other interventions to guarantee the general welfare and the optimal health of the person.
