Getting your doctor to run an annual blood panel can be life changing and life saving. A yearly peek into your internal health helps you get familiar with your baselines and can offer a quick diagnosis if there are any issues. You don’t have to be symptomatic or unwell to get a blood panel done. You can simply request one at your annual physical with your general practitioner. I highly recommend it for several reasons that I will share, especially in the depths of winter.
My husband and I started requesting annual blood panels six or seven years ago. We wanted to know what our baselines were before trying to conceive our first child and also wanted to check that my husband’s vitamin D levels weren’t too low (without proper supplementation his levels can fall off a cliff). Since then, we have done an annual blood panel every year.
You Might Get Paid to Do Bloodwork!
Every year my husband and I upload our bloodwork results into a health benefits portal through my husband’s employer. Not only has this been beneficial for keeping tabs on our health but we actually get paid for doing it. If you get health insurance through your employer it’s worth looking into whether or not they offer health perks or incentives. Many large companies do. Rewards for reporting basic biometrics such as weight, height, age, blood pressure and cholesterol levels (collected through blood analysis) might include a discount on the premium for your health insurance or a cash bonus for your health savings account (HSA). Even if your employer doesn’t offer these benefits, it’s still important to do a blood panel.
Internal vs. External Health
It may seem obvious but external health doesn’t always equate to internal health. Thus, it’s critically important that we occasionally peek into what the blood reveals about our holistic health. An overweight individual doesn’t always have internal risk factors present for diabetes or heart disease. The converse is true for an individual whose weight falls within what is generally deemed a healthy range; this person might have hypertension and high blood sugar that a trip to her GP and a blood panel can reveal.
Sometimes, a blood test is the only way to get answers for health factors that aren’t discernable to the naked eye and don’t always correlate with one’s body weight. For example, a woman complains of chronic fatigue. She is a normal body weight and practices good nutrition. She also maintains a daily exercise schedule. A blood panel can reveal if this fatigue comes from low iron or thyroid dysfunction. If a problem is found then iron supplements or thyroid treatment may begin. If not, the woman might take a closer look at whether she is sleeping enough, feeling undue stress, or over-exercising. Each of these lifestyle factors can also cause crippling fatigue.
What Can Different Blood Panels Evaluate?
- Organ function
- Heart disease risk factors
- Presence of disease (ex: cancer, diabetes)
- Blood clotting factors
- Hemoglobin levels and anemia
- Vitamin deficiencies
- Efficacy of certain medicines
- Clinical allergies (usually requested by allergist not GP)
What are the Most Common Blood Tests?
Below are descriptions of the most common blood tests that doctors do, but the list is not exhaustive. As mentioned, my husband has specifically requested checks on his vitamin D levels before. I have also taken my toddler for two blood analyses for different suspected allergies (milk and soy when he was a baby, almonds as a toddler…all negative). Most recently, I had a blood analysis done to assess my recovery from blood loss during emergency surgery. The panel looked at my hemoglobin levels, red blood cell counts, and the size of my red blood cells. I also asked for a folate and thyroid panel check out of curiosity and a desire for hormonal balance and nutritional well-being. All levels were within normal ranges and I was assured that I had recovered from acute anemia. The peace of mind was wonderful. If something had been “off,” I would have been grateful to know so that I could take swift corrective actions.
Complete Blood Count
What it measures:
Blood diseases and disorders like anemia, clotting issues, blood cancers, and immune system disorders. Components included in a CBC: Red blood cells, white blood cells, platelets, hemoglobin, hematocrit and mean corpuscular volume.
Basic Metabolic Panel
What it measures:
A BMP can reveal information about the heart, organs, muscles and bones by looking at different chemicals typically found in the plasma (fluid) part of the blood. Components included in a BMP: Glucose levels, calcium, electrolytes, and more.
What it measures:
Heart disease risk analyzed through total cholesterol, LDL cholesterol (i.e. “bad” cholesterol), HDL cholesterol (i.e. “good” cholesterol), and triglycerides. This test often requires fasting for 12 hours prior to the blood draw.
As mentioned, there are many reasons to do a blood test. For example, a blood enzyme test can look at enzyme levels related to heart attacks to rule them out or confirm them. Blood clotting tests may be done if your doctor suspects you may have a clotting disorder or before/after certain major surgeries. Even covid-19 patients have been undergoing blood tests at hospital intake to evaluate their risk of mortality based on elevated red cell distribution width (RDW). According to medical professionals, elevated RDW “has previously been associated with an increased risk for morbidity and mortality in a variety of diseases, including heart disease, pulmonary disease, influenza, cancer and sepsis.”
I’m not a doctor. I don’t pretend to be one either. This is why it’s imperative that you become your own health advocate. Ask your doctor for a blood panel on an annual basis. It might simply reassure you that your health is on the right track. Or it might be the thing that helps save your life.
Yours in health and wellness,
