Blood vs. Saliva vs. DUTCH
Hormone testing can provide valuable information about how your body is producing and processing hormones. However, different tests answer different questions. There is no single test that is best for every patient.
🩸 Blood Testing
“How much hormone is circulating in my bloodstream?”
Blood testing is the traditional approach to hormone evaluation and is often the starting point for identifying or monitoring conditions involving:
- Testosterone
- Estrogen
- Progesterone
- Thyroid hormones
- DHEA-S
- Cortisol
- Insulin and other metabolic markers
Best for: Establishing hormone levels and evaluating conventional endocrine conditions.
💧 Saliva Testing
“How much free hormone is present at different times of the day?”
Saliva testing is particularly useful for evaluating cortisol patterns because samples can be collected at multiple points throughout the day. This can provide information about:
- Morning cortisol
- Cortisol throughout the day
- Evening/nighttime cortisol
- The body’s daily cortisol rhythm
Best for: Looking at patterns of free cortisol throughout the day.
🧪 DUTCH Testing
“What are my hormone levels, and how are my hormones being metabolized?”
DUTCH testing uses dried urine samples to evaluate hormones and their metabolites. Depending on the panel, it can provide information about:
- Estrogen and estrogen metabolites
- Progesterone metabolites
- Testosterone and androgen metabolites
- Cortisol and cortisol metabolites
- Daily hormone patterns
One of the unique features of DUTCH testing is that it looks beyond hormone levels to examine how certain hormones are being processed by the body.
Best for: A more comprehensive look at hormone patterns and hormone metabolism, particularly when symptoms are complex or conventional testing doesn’t tell the whole story.
So, Which Test Is Right for Me?
The answer depends on what we’re trying to learn. Blood testing may be appropriate when we need to establish hormone levels or evaluate a specific medical condition. Saliva testing may be useful when we’re interested in daily cortisol patterns. DUTCH testing may provide additional information about hormone metabolism and daily patterns that isn’t available from a single blood test. In some cases, combining conventional blood testing with functional testing can provide a more complete picture.
The Goal Isn’t Just to Test Hormones. It’s to Understand the Bigger Picture.
Your symptoms, medical history, medications, lifestyle, laboratory results, and hormone patterns all need to be considered together. Schedule a consultation to explore whether hormone testing could help provide a clearer picture of your health. Bloomberg Chiropractic Center 618-783-2424.
