Do You Need an STD Test? Here's How to Know

Many STDs show no symptoms, but that doesn’t mean you shouldn’t get tested.

Wondering if you need an STD test?

If you’re showing any symptoms, that’s a good sign it’s time for a test. But the reality is that you can have an STD and not show any symptoms.

So, how do you know if you need a test?

This guide helps you figure out if and when you need an STD test with a simple checklist and risk score tool—so you can stop guessing and take control of your health.

Why It Matters

Many STDs show no symptoms at all. In fact, you could carry an infection like chlamydia, gonorrhea, or HIV for months or years without knowing—putting your health and your partners at risk.

If you’re sexually active, regular testing–even if you have no symptoms–helps ensure your health, your partner’s health, and your peace of mind. 

Plus, most STDs are easily treatable once detected. The earlier you catch them, the easier they are to treat.

For example, according to the CDC, Chlamydia is treatable with a 7 day course of doxycycline. 

Does Age Affect Whether You Should Get an STD Test?

Your age can play a significant role in determining how often you should get tested.

• Young adults under 25: This age group has the highest rates of reported STDs, particularly chlamydia and gonorrhea. The CDC recommends annual testing for all sexually active individuals under 25—regardless of symptoms—due to increased risk.

   

• People 25 and older: While STD rates drop slightly with age, risk still exists—especially if you have multiple partners, new partners, or inconsistent condom use. Adults over 25 should get tested regularly based on lifestyle and risk factors.

• People 55 and older: https://gis.cdc.gov/grasp/nchhstpatlas/charts.html that rates of certain STDs have more than doubled in the past 10 years in people ages 55 and up. If you’re sexually active, you should still get regular testing at any age. 

Bottom line: If you're under 25 and sexually active, testing should be routine. If you’re older, your testing frequency should reflect your relationship status, partner history, and protection use.

What Happens If You Wait Too Long to Get Tested?

Delaying STD testing can lead to serious health consequences—even if you don't have symptoms. Many infections cause long-term damage when left untreated.

Here are some of the risks:

• Infertility: Untreated chlamydia and gonorrhea can lead to pelvic inflammatory disease (PID) in women and epididymitis in men, both of which can cause infertility.
• Increased transmission risk: You may unknowingly pass an STD to a partner, even without symptoms.
• Chronic pain: Conditions like PID can cause long-term abdominal or pelvic pain.
• Pregnancy complications: STDs can lead to miscarriage, stillbirth, or serious health issues for the baby.
• Weakened immune system: HIV and hepatitis can gradually weaken your immune defenses and cause severe illness if not managed early.
• Higher risk of acquiring other STDs: Having one untreated STD increases your susceptibility to others, including HIV.

Testing is quick, confidential, and easy. Waiting increases risk—but early action protects your health and future.

What Are the Signs You Might Have an STD?

While many STDs don’t show symptoms at all, there are still clear signs to watch for. If you’re experiencing any of the following, it’s a strong signal to get tested.

Below is a quick-reference table showing common STD symptoms by infection. 

If you’re experiencing any of the above—or if you’ve had a recent exposure or new partner—schedule a test. Early detection makes treatment simpler and protects others.

When Should You Get an STD Test If You Don’t Have Symptoms?

You don’t need to wait for symptoms to appear before getting tested. Certain life changes or situations are strong indicators that it's time to schedule a test—even if you feel fine.

Here are common scenarios that should trigger you to consider getting tested:

• You started a new relationship
  Even if you trust your new partner, it’s smart to get a baseline test before becoming sexually active—or before you stop using protection.
• You and your partner stopped using condoms or dental dams
  Removing barrier protection increases your risk of exposure to STDs, even in committed relationships.
• You recently broke up or had a casual encounter
  Testing after a breakup or hookup gives you peace of mind and helps protect future partners.
• You found out a past partner tested positive
  Even if the relationship ended months ago, some STDs take time to show up—or show no symptoms at all.
• You're entering a pregnancy or fertility journey
  Most prenatal care includes STD testing, but it’s helpful to get ahead of it, especially if trying to conceive.
• You haven’t been tested in over a year
  If you’re sexually active—even with one partner—it’s a good idea to test annually.

Think of these moments as natural check-in points for your sexual health. A quick test now can prevent complications and protect your current or future partner.

Frequently Asked Questions (FAQ)

How soon after sex should I get tested?

Can I get tested if I don't have symptoms?

Will my test results be private?

• Yes. Clinics and at-home services must follow strict confidentiality rules. You can also ask about anonymous HIV testing at some locations.

Does my partner need to get tested too?

• Absolutely. If you test positive, your partner should get tested and treated to prevent reinfection.

Can I use an at-home test?

• Yes. At-home kits are a good option for privacy and convenience. Just make sure they're FDA-approved and include a full panel if you need it.

What if I test positive?
