Sodium is checked to assess fluid balance, hydration, and how your kidneys and hormones manage water. Clinicians order it for symptoms like weakness, confusion, cramps, or when using diuretics or IV fluids. Results can guide steps such as reviewing medicines, adjusting fluids, or checking urine and kidney tests. You can test this marker with Aniva across Germany and Finland.

High: Often from losing more water than salt (dehydration), extra salt intake, or certain medicines. You may feel very thirsty or weak.
Low: Often from extra body water, diuretics, vomiting, or hormone and organ conditions. Headache, nausea, or confusion can occur when very low. Trends and symptoms guide next steps; clinicians may review fluids, medicines, urine tests, and kidney function.
Common factors that can skew results include unusual fluid intake, heavy sweating, vomiting or diarrhea, recent IV fluids, and medicines like diuretics, SSRIs, ACE inhibitors, NSAIDs, or steroids. Marked high blood sugar, very high triglycerides, or very high proteins can affect some lab methods. Pregnancy can slightly lower sodium.
Special situations: results during IV fluids, extreme lipids or proteins, or marked high blood sugar may need confirmation or correction with your clinician.
What does my sodium result mean? It reflects your body’s fluid and salt balance. High or low levels suggest issues with water balance, medicines, or health conditions.
Do I need to fast for a sodium test? No. Eat and drink normally unless your clinician gives different instructions.
What can affect my result? Water or salt intake, diuretics, antidepressants, NSAIDs, steroids, recent IV fluids, sweating, vomiting, or pregnancy can shift levels.
How often should I test sodium? As advised by your clinician, especially if you take diuretics, have symptoms, or are being treated for low or high sodium.
How quickly will I get results? Most labs report sodium within 1–2 business days.
What should I discuss with my clinician? Tell them about your symptoms, fluid intake, all medicines and supplements, and ask if urine tests or kidney checks are needed.
