Annual lab work is one of the more practical components of preventive care. A blood panel can provide information about how key organ systems are functioning, identify changes in metabolic health, and flag values that may warrant closer attention, often before any symptoms are present.
This article provides a general educational overview of lab tests that are commonly discussed in the context of adult preventive care. It does not specify which tests are right for any individual, as that depends on age, sex, health history, and other factors assessed during a clinical evaluation at ProMed Longevity + Primary Care or with another qualified provider.
Why Does Routine Lab Work Matter?
Several conditions that affect long-term health develop gradually and without obvious symptoms. Elevated blood glucose, high cholesterol, kidney function decline, and thyroid dysfunction can all progress silently for a period before causing noticeable problems. Routine lab work creates a record of your health over time, making it easier to identify changes and respond to them appropriately.
The specific tests ordered at any given visit depend on your age, existing conditions, family history, current medications, and clinical judgment. There is no single universal panel appropriate for every adult.
What Is a Comprehensive Metabolic Panel?
A comprehensive metabolic panel (CMP) is a group of tests that assesses several areas of metabolic function simultaneously. It typically includes:
- Glucose: A measure of blood sugar at the time of the draw, relevant to diabetes screening and management
- Kidney function markers including creatinine and blood urea nitrogen (BUN), which reflect how well the kidneys are filtering waste
- Electrolytes including sodium, potassium, calcium, and bicarbonate, which affect fluid balance and organ function
- Liver function markers including ALT, AST, alkaline phosphatase, and bilirubin
- Total protein and albumin, which can reflect nutritional status and liver function
A CMP provides a broad snapshot of metabolic health and is frequently ordered as part of a routine wellness panel.
What Is a Lipid Panel?
A lipid panel measures cholesterol and related fats in the blood. Standard components include:
- Total cholesterol
- LDL cholesterol (low-density lipoprotein), often referenced in the context of cardiovascular risk
- HDL cholesterol (high-density lipoprotein)
- Triglycerides
Lipid panels are used to assess cardiovascular risk, and the frequency with which they are ordered depends on your individual risk profile and prior results. Some patients may have additional markers ordered alongside a standard lipid panel based on their cardiovascular history or family history.
What Is an HbA1c Test?
HbA1c, also called hemoglobin A1c or glycated hemoglobin, is a measure of average blood glucose over approximately the previous two to three months. Unlike a fasting glucose test, which reflects blood sugar at a single point in time, HbA1c provides a broader picture of glucose control.
It is used in the evaluation and ongoing management of diabetes and prediabetes. Whether it is ordered annually depends on your current health status, risk factors, and prior results.
What Is a Complete Blood Count?
A complete blood count (CBC) measures the different types of cells in your blood, including red blood cells, white blood cells, and platelets. It can provide information relevant to anemia, immune function, and other conditions. It is a commonly ordered part of routine preventive lab work for many adults.
What About Thyroid Testing?
Thyroid function testing, typically a TSH (thyroid-stimulating hormone) level, is used to evaluate how well the thyroid gland is functioning. Thyroid disorders are relatively common and can affect energy levels, weight, mood, and other areas of health. The frequency with which thyroid testing is recommended depends on your symptoms, prior results, and risk factors.
How Do You Prepare for a Routine Blood Draw?
Preparation requirements vary depending on which tests are being ordered. Some panels, including certain glucose and lipid tests, require fasting for a specified period beforehand, typically eight to twelve hours, during which only water is generally permitted. Other tests do not require fasting at all. A provider or the lab will give specific fasting instructions when the tests are ordered.
Staying well hydrated before a blood draw can make the process easier, since adequate hydration supports vein visibility. Patients should disclose current medications and supplements to their provider beforehand, since some can affect certain results. Wearing a short-sleeved shirt or one with sleeves that can be easily rolled up makes the draw more straightforward. Bringing a photo ID and insurance card is generally recommended for any lab visit, and arriving a few minutes early allows time for check-in.
How Long Do Lab Results Take and How Will You Receive Them?
Turnaround time depends on the specific tests ordered. Many routine panels, such as a comprehensive metabolic panel or complete blood count, are typically available within a day or two, while some specialized tests can take longer. The lab or provider’s office can give a more specific estimate for the panel that was ordered.
At ProMed, results are generally reviewed with the patient once they are available. If a question comes up before a scheduled follow-up, patients can contact the office directly. Reading a result on a patient portal is not a substitute for clinical interpretation. Reference ranges printed on a lab report are general population values, and a specific result often needs to be considered alongside the patient’s health history, symptoms, and other lab findings to have clinical meaning.
Are There Additional Tests Worth Discussing?
Depending on your individual clinical picture, a provider may also discuss:
- Vitamin D level, particularly relevant for patients with limited sun exposure, certain health conditions, or symptoms that may be associated with deficiency
- Iron studies and ferritin, relevant in the context of fatigue or anemia evaluation
- Inflammatory markers such as hsCRP (high-sensitivity C-reactive protein) in the context of cardiovascular risk assessment
- Hormone levels including testosterone, estradiol, or thyroid hormones, depending on symptoms and health history
- Urinalysis, which can provide information about kidney function and detect certain conditions
At ProMed’s diagnostic screenings service, lab work is ordered and reviewed in the context of a clinical evaluation, not as a standalone product. Your provider reviews results with you and discusses their relevance to your individual health picture.
Frequently Asked Questions
What blood tests should I get every year?
The most commonly recommended routine blood tests for adults include a comprehensive metabolic panel, lipid panel, complete blood count, and blood glucose or HbA1c. Thyroid function testing is also commonly ordered. The specific tests appropriate for you depend on your age, sex, health history, and risk factors, and are determined by your provider during a clinical evaluation.
What is a diagnostic screening?
Diagnostic screening refers to testing performed to evaluate health status or identify potential concerns, often before symptoms are present. In a primary care setting, this typically includes blood work, vital measurements, and other assessments ordered based on clinical guidelines and individual patient factors.
Do I need to fast before a lab test?
Some tests, including certain glucose and lipid panels, are more accurate when the patient has fasted for a specified period beforehand. Others do not require fasting. Your provider or the lab will give you specific instructions when your tests are ordered. When in doubt, ask before your appointment.
Can I request specific lab tests at ProMed?
You can discuss your health concerns and areas of interest with your provider, who will determine which tests are clinically appropriate based on your health history. Lab work is ordered based on a clinical evaluation, not as an à la carte service. If you have specific questions about which tests may be relevant for you, bring them to your appointment.
