*🧪 #quicklabfact* 🧫⚠️ Potassium (K⁺) levels can be falsely elevated due to hemolysis! 🩸 When red blood cells rupture during or after collection, they release intracellular potassium into the serum or plasma. 🚨 Causes of hemolysis include: • Using a small needle gauge • Excessive force during blood draw • Vigorous shaking of the tube • Delayed separation of serum/plasma ❗ Falsely high K⁺ = Misleading diagnosis (e.g., pseudohyperkalemia) Always repeat critical results with a non-hemolyzed sample! 📌 Proper phlebotomy = Reliable electrolytes ⚖️ ‎Follow the نبض المختبر Lab Pulse channel on WhatsApp: https://whatsapp.com/channel/0029Vaydi9IBKfi318dkau32
