Comprehensive Metabolic Panel

The Comprehensive Metabolic Panel (CMP) is a blood test that gives doctors information about the body's fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys and liver are working. This broad screening tool includes 14 different measurements that evaluate the way your body is using its energy. These measurements encompass liver and kidney health, blood sugar, metabolism, and your body’s balance of electrolytes such as sodium and potassium. When reviewed by your doctor along with other tests and information from a clinical examination, a CMP can be useful in detecting certain conditions including diabetes, kidney disease, and hypertension.

Why might you need a Comprehensive Metabolic Panel (CMP)? If you're experiencing symptoms such as fatigue or vomiting, a CMP may be able to identify the cause of the symptoms. A CMP may also be ordered to monitor certain chronic conditions you may have, such as high blood pressure or kidney disease. If you had a prior test result that was abnormal to see if your levels have changed or remain abnormal.

Lipid Panel

A Lipid Panel is a group of tests which measures the amount of cholesterol, triglycerides, and other fats (lipids) in your blood. These fats are important for cell health, but they can be harmful when they build up in the blood. An excess amount of blood lipids can cause fat deposits in your artery walls, increasing your risk for heart disease.

A Lipid Panel usually gives results for four different types:

  • Total cholesterol.
  • LDL (low-density lipoprotein), the "bad cholesterol"
  • HDL (high-density lipoprotein), the "good cholesterol"
  • Triglycerides, the most common type of fat in your body.

Why might you need a Lipid Panel test? Doctors often order a lipid panel as part of routine blood work during a physical examination. This routine test helps to determine if your cholesterol level is normal or falls into a borderline-, intermediate- or high-risk category. This test may also be used to monitor your cholesterol level if you had abnormal results on a previous test or if you have other risk factors for heart disease. The Lipid Panel test assesses a patient's risk of developing cardiovascular disease, which includes heart attacks and strokes.

Complete Blood Count

A Complete Blood Count (CBC) test is used to evaluate your overall health and detect a wide range of disorders, including anemia, autoimmune disorders, bone marrow disorders, lymphoma, sickle cell disease, and leukemia. It can also identify an infection, as well as dehydration and nutritional deficiencies. Abnormal increases or decreases in cell counts as revealed in a complete blood count may indicate that you have an underlying medical condition that calls for further evaluation. A complete blood count test measures several components and features of your blood, including:

  • Red blood cells, which carry oxygen
  • White blood cells, which fight infection
  • Hemoglobin, the oxygen-carrying protein in red blood cells
  • Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood
  • Platelets, which help with blood clotting

Why might you need a Complete Blood Count (CBC) test? A CBC allows providers to screen for diseases and adjust treatments. The CBC helps healthcare providers detect a range of disorders and conditions as well as checks your blood for signs of medication side effects.

Urinalysis

Urinalysis is a urine test which screens for possible problems with your metabolism and kidneys by examining the appearance, concentration, and content in your urine including the amount of protein, glucose, and other substances that may indicate various health conditions. Urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease, liver disease, and diabetes.

Why might you need a Urinalysis (urine test)? Healthcare providers often use urinalysis tests to screen for or monitor certain health conditions and to diagnose urinary tract infections. Your doctor may recommend a urinalysis test if you have symptoms that could be related to problems with the liver, kidneys, or urinary system. If you are having frequent or painful urination, blood in your urine, other urinary difficulties, or ongoing abdominal or back pain, your doctor may recommend a urinalysis to help determine the cause of these symptoms. Additionally, a screening urinalysis test may be recommended if you have an upcoming surgery, are pregnant, or as part of a regular medical checkup. If you have a medical condition such as kidney disease or diabetes, your doctor may advise you to have regular urine tests to monitor your condition and treatment.

Thyroid Stimulating Hormone

A Thyroid Stimulating Hormone (TSH) test is a common blood test used to evaluate how well the thyroid gland is working. The thyroid gland is located at the lower front of the neck, and is responsible for hormones that regulate the way your body uses energy, as well as regulating your weight, body temperature, muscle strength, and even your mood. Thyroid Stimulating Hormone (TSH) is produced by the pituitary, a pea-sized gland located at the base of the brain. When thyroid levels in your body are low, the pituitary gland makes more TSH. When thyroid levels are high, the pituitary gland makes less TSH. TSH levels that are too high or too low can indicate your thyroid isn't working correctly. A TSH test is the blood test used to measure this hormone.

Why might you need a Thyroid Stimulating Hormone (TSH) test? You may need a TSH test if you have symptoms of too much thyroid hormone in your blood (hyperthyroidism), or too little thyroid hormone (hypothyroidism).

Symptoms of hyperthyroidism, also known as overactive thyroid, include:

  • Anxiety
  • Weight loss
  • Tremors in the hands
  • Increased heart rate
  • Puffiness
  • Bulging of the eyes
  • Difficulty sleeping

Symptoms of hypothyroidism, also known as underactive thyroid, include:

  • Weight gain
  • Tiredness
  • Hair loss
  • Low tolerance for cold temperatures
  • Irregular menstrual periods
  • Constipation

Hemoglobin A1C

The Hemoglobin A1C test (also called the glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C or HbA1c test) is a common blood test used to diagnose type 1 and type 2 diabetes. The hemoglobin A1c test estimates how much glucose, or blood sugar, has been in your bloodstream over the last three months. The A1C test works by measuring what percentage of hemoglobin proteins in your blood are coated with sugar (glycated). The higher your A1C level is, the poorer your blood sugar control and the higher your risk of diabetes complications.

Why might you need a Hemoglobin A1C test? This common test is used to diagnose prediabetes and diabetes, and is also the main test utilized in managing diabetes. People who have diabetes need this test regularly to monitor how well they are managing blood sugar levels and to see if their hemoglobin levels are staying within an optimal range. The Hemoglobin A1C test can determine if you need to adjust your diabetes medicines. The hemoglobin A1c test is not used to diagnose gestational diabetes, a form of the disease that can develop during pregnancy.
