As the year draws to a close, it’s easy to get caught up in holiday preparations and plans. However, it’s also the perfect time to prioritize your health by checking in with your body.

Regular lab tests can help detect underlying health issues, allowing you to address potential problems before they become serious. Whether you’re feeling perfectly fine or experiencing minor symptoms, these 10 essential lab tests should be on your to-do list before the year ends.

1. Complete Blood Count (CBC)

A Complete Blood Count is a basic yet highly informative test that evaluates the overall health of your blood cells. It measures red blood cells (which carry oxygen), white blood cells (which fight infections), and platelets (which help blood clotting). Abnormal CBC results can indicate a range of conditions, from anemia and infections to more serious diseases like leukemia.

  • Why you need it: This test can uncover infections, blood disorders, and even give early clues about cancer.
  • When to do it: Annually, especially if you experience fatigue, weakness, or frequent infections.

2. Lipid Profile (Cholesterol Test)

A lipid profile measures the levels of fats in your blood, including cholesterol (HDL and LDL) and triglycerides. High cholesterol and triglyceride levels can increase the risk of heart disease, stroke, and other cardiovascular problems.

  • Why you need it: Early detection of high cholesterol can help prevent heart disease and stroke.
  • When to do it: Every 1-2 years if you’re over 20 or more frequently if you have risk factors like obesity, smoking, or a family history of heart disease.

3. Blood Sugar Test (Fasting Glucose)

A fasting blood sugar test measures the level of glucose (sugar) in your blood after you haven’t eaten for at least 8 hours. This test is crucial for detecting prediabetes, diabetes, and how well your body is managing sugar.

  • Why you need it: Early detection of high blood sugar can help prevent or manage diabetes, which can lead to complications like heart disease, kidney problems, and vision loss.
  • When to do it: Annually, especially if you are overweight, have a family history of diabetes, or have experienced unusual thirst or frequent urination.

4. Thyroid Function Test (TFT)

The thyroid function test measures the levels of thyroid hormones (TSH, T3, and T4) in your blood. Your thyroid gland regulates metabolism, energy levels, and overall hormone balance. Abnormal thyroid levels can indicate conditions like hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid).

  • Why you need it: Thyroid imbalances can cause fatigue, weight gain or loss, depression, and more. Testing helps catch these conditions early.
  • When to do it: Every few years, but more frequently if you experience symptoms like unexpected weight changes, fatigue, or mood swings.

5. Vitamin D Test

Vitamin D is essential for bone health, immune function, and mental health. A deficiency can lead to bone disorders such as osteoporosis or rickets, and increase your risk for infections and autoimmune diseases. A vitamin D test measures the amount of vitamin D in your blood.

  • Why you need it: Low levels can affect bone health and immunity, especially in people who live in areas with little sunlight.
  • When to do it: Annually, especially during or after winter when sunlight exposure is minimal.

6. Liver Function Test (LFT)

Liver function tests measure enzymes and proteins in your blood that indicate how well your liver is functioning. This test helps detect liver damage, inflammation, or disease. Common liver conditions include hepatitis, fatty liver disease, and cirrhosis.

  • Why you need it: The liver is vital for detoxifying your body and aiding digestion. Early detection of liver problems can prevent severe damage.
  • When to do it: Annually, or more frequently if you consume alcohol regularly, take medications that may affect the liver, or have liver disease risk factors.

7. Kidney Function Test (Creatinine and BUN)

This test evaluates how well your kidneys are filtering waste products from your blood. It measures levels of creatinine and blood urea nitrogen (BUN), which indicate how efficiently your kidneys are functioning. High levels may signal kidney disease or impaired kidney function.

  • Why you need it: Kidney disease often shows no symptoms until it’s advanced, so early testing can help prevent kidney failure.
  • When to do it: Annually, especially if you have high blood pressure, diabetes, or a family history of kidney disease.

8. C-Reactive Protein (CRP) Test

CRP is a protein produced by your liver in response to inflammation. A CRP test measures the level of this protein in your blood and can indicate the presence of inflammation or infection. High levels may suggest an increased risk of heart disease, autoimmune diseases, or infections.

  • Why you need it: Elevated CRP levels can signal inflammation linked to heart disease, autoimmune conditions, or infections.
  • When to do it: Every couple of years or more frequently if you have symptoms of chronic inflammation or heart disease risk factors.

9. Hemoglobin A1C (HbA1C) Test

The Hemoglobin A1C test provides an average of your blood sugar levels over the past 2-3 months. Unlike a fasting glucose test, this gives a longer-term view of blood sugar control and is crucial for diagnosing prediabetes and diabetes.

  • Why you need it: It offers a more comprehensive picture of your blood sugar levels over time, allowing for early detection of diabetes.
  • When to do it: Annually, especially if you have risk factors for diabetes or previously had abnormal blood sugar results.

10. Sexually Transmitted Infection (STI) Panel

An STI panel checks for common sexually transmitted infections, including HIV, syphilis, gonorrhea, and chlamydia. Many STIs can be asymptomatic, meaning they show no symptoms but can cause long-term health issues if left untreated.

  • Why you need it: Early detection and treatment can prevent the spread of STIs and avoid complications such as infertility or organ damage.
  • When to do it: Annually, or more frequently if you have multiple sexual partners or engage in unprotected sex.
