What is a Thyroid Screening? Demystifying Blood Tests at Neshoba General

Have you been feeling unusually exhausted, experiencing sudden changes in your weight, or feeling constantly too hot or too cold? While it is easy to blame a hectic schedule, these subtle shifts are often signs that your thyroid gland needs attention.

The thyroid is a small, butterfly-shaped gland found at the base of your neck. Despite its small size, it acts as your body’s internal control center, producing hormones that regulate your metabolism, energy levels, body temperature, and heart rate. A simple, routine blood test called a thyroid screening is all it takes to find out if your thyroid is functioning properly.

Common Signs Your Thyroid May Be Out of Balance

When your thyroid produces too much or too little hormone, your entire system can feel off.

• Hypothyroidism (Underactive Thyroid): This occurs when the gland does not produce enough hormone. Common symptoms include persistent fatigue, unexplained weight gain, dry skin, constipation, and feeling unusually sensitive to cold temperatures.
• Hyperthyroidism (Overactive Thyroid): This happens when the gland produces too much hormone. Symptoms can include sudden weight loss, a rapid or irregular heartbeat, anxiety, irritability, and sweating.

What Happens During a Thyroid Screening?

A thyroid screening is a quick, minimally invasive blood test. The primary test performed is a TSH (Thyroid-Stimulating Hormone) test. Your body uses TSH to signal how much thyroid hormone to make. If your TSH levels are unusually high or low, it tells your doctor exactly how your thyroid is behaving.

There is no complex preparation required for a standard thyroid blood test. You can visit our outpatient laboratory facility, have your blood drawn in just a few minutes, and head right back to your regular day.

❓Frequently Asked Questions About Thyroid Tests

Do I need to fast before a thyroid blood test?

In most cases, fasting is not required for a standalone TSH or thyroid screening. However, if your doctor has ordered other blood panels at the same time—such as a lipid panel or blood glucose test—you may need to avoid eating or drinking for several hours. Always follow the specific instructions provided by your doctor.

How long does it take to get thyroid test results back?

Because Neshoba General features an advanced on-site laboratory, most routine thyroid blood panel results are completed and sent to your ordering physician within 24 to 48 hours.

Can I get a thyroid test at Neshoba General if my doctor is located outside of Philadelphia, MS?

Yes. The Neshoba General Laboratory routinely processes orders from out-of-town specialists and physicians. Simply bring your physical doctor’s order form or have your clinic fax it directly to our diagnostics department to have your blood drawn locally.
