If you've been struggling with acne for years, you've probably had this thought:


"If blood tests could help explain my acne, why has no one ever suggested them before?"


It's a fair question.


Many of my patients come to their first appointment assuming there isn't much that can be tested. They've often been told that acne is simply hormonal, genetic, or something they'll eventually outgrow. Some have never had any bloodwork done specifically because of their skin.


Then, when working with me, I recommend a panel of blood tests. It's understandable to wonder why. The answer isn't that your family doctor has missed something or isn't doing their job. It's that family physicians and naturopathic doctors often use laboratory testing for different purposes.

Tracey's Story

Tracey was 27 and had struggled with acne since high school. She had tried multiple skincare products, prescription creams, and even adjusted her diet after seeing advice online. Some things helped temporarily, but the breakouts always returned.


Her family doctor had ordered bloodwork in the past to check her general health, and everything came back "normal."


So when I recommended another set of blood tests, she was confused. Why repeat testing if she'd already been told everything looked fine?


The answer came down to one important difference: We weren't asking the same questions.

Family Doctors and Naturopathic Doctors Have Different Goals

Family physicians are trained to diagnose disease and rule out serious medical conditions.


If someone has symptoms suggesting anemia, diabetes, thyroid disease, liver disease, or another medical condition, bloodwork is incredibly valuable for making or excluding those diagnoses. If those tests come back within the laboratory reference range, there may be no medical diagnosis requiring treatment.


That doesn't mean your skin has been fully investigated.


When I order bloodwork for acne, I'm often looking for patterns, trends, and factors that may influence skin health, even if they don't meet the criteria for a medical diagnosis.


Rather than asking: "Do you have a disease?"


I'm also asking: "Is there anything affecting your skin that we can improve?"

Acne is Rarely Caused By One Thing

Acne develops because several biological processes interact. These include:

  • Hormone activity
  • Inflammation
  • Blood sugar regulation
  • Skin oil production
  • Immune function
  • Genetics
  • Gut health
  • Nutrition


Blood testing doesn't capture every one of these factors. It also doesn't diagnose acne. Instead, it helps us understand whether there are modifiable contributors that may be making acne more difficult to improve.

What Blood Tests Might Be Helpful?

Every patient is different, so testing should always be individualized. Depending on your symptoms and history, bloodwork may help assess areas such as:


Inflammation

  • Markers of inflammation can provide insight into whether chronic, low-grade inflammation may be contributing to your skin.
  • Inflammation doesn't cause every case of acne, but it plays a major role in the formation of inflamed pimples and cysts.


Blood sugar regulation

  • Many people think diabetes is the only blood sugar problem.
  • In reality, blood sugar can fluctuate long before someone develops diabetes.
  • Poor blood sugar regulation may contribute to increased insulin levels, which can stimulate pathways involved in oil production and acne development.


Nutrient status

  • Your skin is one of the body's most metabolically active organs, constantly repairing itself, regulating inflammation, and producing new cells. To do this efficiently, it relies on an adequate supply of vitamins, minerals, and other nutrients.
  • Blood testing can sometimes identify nutrient deficiencies or imbalances that may be affecting your overall health and, in some cases, making it more difficult for your skin to function optimally.
  • It's also worth remembering that more isn't always better. Some nutritional supplements can actually worsen acne in certain individuals, which is another reason why testing and individualized assessment can be valuable before making changes to your supplement routine.


Hormones

  • Not everyone with acne needs hormone testing.
  • However, if someone has irregular periods, excessive facial hair, scalp hair thinning, or acne that strongly suggests an underlying hormonal condition, hormone testing may be appropriate.

Blood Testing Is Only One Piece Of The Puzzle

A common misconception is that bloodwork will reveal the cause of acne. 


Unfortunately, it doesn't work that way. Many important contributors to acne cannot be measured through blood testing alone. For example:

  • Your gut microbiome
  • Skincare habits
  • Cosmetic products
  • Stress
  • Sleep quality
  • Dietary patterns
  • Genetics
  • Skin barrier function


This is exactly why my Breakthrough Acne Program doesn't rely on lab work alone. Blood testing is simply one tool that helps build a more complete picture.

Ready To Understand What's Driving Your Acne?

Knowing which tests are appropriate is only the first step. Equally important is understanding why they're being ordered, how to interpret the results in the context of your health, and how they fit into an overall plan for improving your skin.


In my Breakthrough Acne Program, bloodwork is never ordered "just because." Each test is chosen based on your individual history, symptoms, and clinical presentation. The results are then reviewed alongside other aspects of your health—including digestion, nutrition, stress, hormones, skincare, and lifestyle—to help identify factors that may be making your acne harder to manage.


Because acne is usually influenced by multiple systems in the body, taking a comprehensive, personalized approach often provides far more useful information than focusing on a single lab value.


If you've been told your bloodwork is "normal" but you're still struggling with acne, it may be time to look at the bigger picture. Watch my free webinar: 3 Reasons Your Acne Isn't Clearing (That Your Doctor Never Told You) to learn why acne is often more complex than it appears and the three root causes I investigate most often.
