Why would I choose blood spot testing over saliva or blood serum testing?
Blood spot testing offers highly accurate results comparable to traditional serum testing but without the expense and inconvenience of standard blood draws. This method eliminates the need for lab visits and uncomfortable venipunctures by allowing you to conveniently collect samples at home or at your doctor’s office.
This approach is also great for individuals using sublingual or troche hormone supplements, as it avoids the falsely elevated readings often associated with saliva testing. Since these supplements can leave hormone residues in the mouth, blood spot testing provides a more accurate assessment without the need to pause supplementation. Blood spot testing also benefits those with dry mouth conditions, like Sjogren’s Syndrome, or anyone who may struggle to produce enough saliva for testing. Additionally, specific tests—such as those for thyroid function, —are exclusively available in blood spot form. Blood spot testing is also great if you:
- Use sublingual (under the tongue) or troche hormone supplements
- Experience dry mouth or cannot produce enough saliva
- Prefer a simple finger stick to a blood draw
- Need to measure hormones or markers only available through blood spot
How are finger-stick dried blood spot and venipuncture blood serum different?
Dried blood spot testing uses a small sample of whole blood collected from a fingertip, primarily containing capillary blood, unlike venous blood drawn from the arm. Capillary blood is rich in nutrients, hormones, and oxygen as it flows to nourish tissues, whereas venous blood has partially depleted these resources, preparing to recirculate through the heart, lungs, and digestive tract for reoxygenation and nutrient loading.
Unlike serum, which is separated from whole blood and only includes the fluid portion, dried blood spots maintain the full composition of whole blood, including blood cells. This means any hormones bound to cells are retained in the sample, leading to a more complete reflection of capillary blood hormone levels. Since capillary blood is the source that directly feeds your tissues, testing it provides a more precise indication of hormone levels affecting your body’s cells.
Are hormone results from blood spots different from conventional venipuncture serum?
The answer varies. For hormones naturally produced by the body (endogenous) or slowly administered through a transdermal patch (like an estradiol patch) or pellet, hormone levels from dried blood spot testing are nearly identical to those from traditional serum tests. Blood spot ranges for these cases closely match serum ranges, providing similar insights.
However, when hormones are delivered rapidly via the skin or mucous membranes—such as with topical or sublingual estradiol, progesterone, or testosterone—capillary blood (collected by finger stick) and tissue levels can be significantly higher than those in venous blood. In such cases, blood spot testing gives a more accurate measure of the actual hormone levels reaching tissues, making it preferable for evaluating the effects of topicals and sublinguals.
Are there any special precautions to take when collecting blood spots?
Yes, it’s important to take precautions if applying hormones topically by hand, as hormone residue can concentrate in the fingers, leading to falsely elevated test results. Hormones absorbed through the skin on your hands may take 12-24 hours to disperse evenly through the body. To avoid this, apply topical hormones without using your fingers—such as rubbing wrists together—for at least two days before testing. Avoid using anti-aging creams that may contain hormone traces as well. Continue with your usual hormone routine, simply avoiding hand exposure.
What time of month should I collect my sample?
Since this test focuses solely on thyroid hormones, it can be done at any time.
When can I test if I am taking hormones?
Do not discontinue current hormone therapy before sample collection. Continue using hormones daily as usual.
