In our recent blog, The Blood Behind the Boom: Top 5 Lab Tests America Can’t Stop Ordering in 2025, we highlighted the most-ordered individual lab tests in the U.S.—tests like CBC, CMP, and A1c that appear frequently in annual checkups and preventive panels.

But several readers asked a great question:
“Why didn’t STD testing make the Top 5?”

The short answer? It’s not a matter of importance—it’s a matter of classification.
And the full story shows just how vital—and popular—STD testing truly is in 2025.

Understanding the Numbers

The Top 5 list was based on the most-ordered standalone lab tests, ranked by volume across all medical categories. These tests are often ordered individually and coded separately in electronic medical systems.

In contrast, STD tests are commonly ordered as part of multi-test panels, such as:

• 3-Panel STD Test (Chlamydia, Gonorrhea, Trichomoniasis)
• 5-Panel STD Test (adds HIV and Syphilis)
• Complete STD Panels (including Hepatitis, HSV, etc.)

Since these are bundled and coded differently, they don’t show up in rankings of individual test volumes—but that doesn’t mean they aren’t widely used.

In fact, STD testing is one of the most in-demand diagnostic categories, especially in direct-to-consumer (DTC) and digital healthcare models.

A Growing Health Priority

With increased awareness and the rise of discreet, user-friendly testing options, more people are proactively testing for STDs than ever before:

• Millions of Americans undergo STD testing each year, often as part of wellness screenings, fertility planning, or employer health programs.
• Gen Z and Millennials are leading the shift toward digital-first, confidential testing options.
• At Lab Testing API, STD panels rank among our top-selling specialty test kits, showing clear demand for accessible and reliable sexual health tools.
