The Baseline Bloodwork

Your doctor will likely start with some basic blood tests. A complete blood count (CBC) can check for signs of infection or blood disorders. Thyroid function tests may be ordered to rule out hyperthyroidism. If you're at risk for HIV, an HIV test might be recommended. These tests provide a broad overview of your health and can point towards potential causes of night sweats.

Imaging Insights

Depending on your symptoms and initial test results, your doctor might order imaging studies. A chest X-ray is often used to check for tuberculosis or lymphoma. In some cases, more detailed imaging like CT scans or PET scans might be necessary to look for hidden tumors or infections. These scans can provide a detailed view of your internal organs and help identify any abnormalities.
Night sweats refer to excessive sweating during the night that can soak through your bedclothes and sheets. This symptom may indicate an underlying medical condition.

Specialized Studies

If initial tests don't provide answers, more specialized studies might be needed. For example, if a hormone-producing tumor is suspected, your doctor might order tests to check hormone levels in your blood or urine. In rare cases, a bone marrow biopsy might be recommended to check for certain blood disorders or cancers. While these tests might sound intimidating, they're valuable tools for getting to the root of persistent night sweats.

Sleep Studies

Sometimes, night sweats can be related to sleep disorders. Your doctor might recommend a sleep study, where you're monitored overnight in a sleep lab. This can help diagnose conditions like sleep apnea, which has been associated with night sweats in some people. During a sleep study, various aspects of your sleep are monitored, including brain waves, heart rate, and breathing patterns.
