If you’re planning to tie the knot, you might be wondering: Do I need a blood test to get married? While that might sound outdated, it’s actually a question many couples still ask — and the answer depends on where you live.
Let’s break down the history, purpose, and current requirements of blood tests for marriage licenses in the U.S. and beyond.
Why Were Blood Tests Ever Required?
Historically, several U.S. states required blood tests before issuing a marriage license. The main purpose was to:
- Screen for infectious diseases, such as syphilis or rubella
- Prevent the spread of genetic conditions
- Protect public health, especially when prenatal health was a concern
These tests were introduced in the 20th century, when there was limited medical screening and treatment options available.
Do You Still Need a Blood Test Today?
In most places, the answer is no.
As of today, no U.S. state requires a blood test for marriage, with the exception of Montana, which still requires a rubella test for women. However, even in Montana, this requirement can be waived with a simple signature.
Here’s a Quick Breakdown:
| State | Blood Test Required? |
|---|---|
| California | No |
| Texas | No |
| New York | No |
| Florida | No |
| Montana | Yes (rubella test for women) |
| All Others | No |
✅ Note: Requirements can change, so always check with your local county clerk or marriage license office.
What Do You Need to Get Married Instead?
Even though blood tests are mostly a thing of the past, here’s what you typically need to get a marriage license:
- A valid government-issued photo ID (e.g., passport or driver’s license)
- Social Security number (in the U.S.)
- Proof of divorce (if applicable)
- Application fee
- Both partners present at the time of application
Some states may have a waiting period after applying before you can officially marry.
Why Did Blood Test Laws Change?
Blood test requirements have largely been eliminated due to:
- Advances in medical screening and treatment
- Improved public health education
- Cost and time concerns for couples and agencies
Today, couples are expected to make informed health decisions on their own or with the help of a healthcare provider.
