Properly\u003c\/strong\u003e\u003cbr\u003eProper technique ensures accurate test results and prevents sample rejection at the laboratory.\u003cbr\u003eStep 1: Inspect the tube for cracks, vacuum loss, or expired date before patient use.\u003cbr\u003eStep 2: Prepare the patient with proper venipuncture technique and tourniquet application.\u003cbr\u003eStep 3: Insert the multi-sample needle into the tube holder and prepare for collection.\u003cbr\u003eStep 4: Follow the standard order of draw if collecting multiple tube types together.\u003cbr\u003eStep 5: Push the tube onto the needle — vacuum draws blood automatically.\u003cbr\u003eStep 6: Allow the tube to fill completely to the indicated 10 mL volume line.\u003cbr\u003eStep 7: Remove the filled tube and gently invert 5 times to mix any activator.\u003cbr\u003eStep 8: Label the tube immediately with patient identifiers and collection time clearly.\u003cbr\u003eStep 9: Allow the tube to clot at room temperature for 30 minutes minimum.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to Process After Collection\u003c\/strong\u003e\u003cbr\u003eAfter collection, follow proper handling steps to preserve sample integrity for accurate testing:\u003cbr\u003eStep 1: Stand the tube upright in a rack during the 30-minute clotting period.\u003cbr\u003eStep 2: Centrifuge at 1500g for 15 minutes after clotting finishes completely.\u003cbr\u003eStep 3: Inspect the spun tube — clear yellow serum should appear above the cellular clot.\u003cbr\u003eStep 4: Aliquot or test the serum within 2 hours of centrifugation for best stability.\u003cbr\u003eStep 5: Refrigerate samples at 2-8°C if testing is delayed beyond 2 hours.\u003cbr\u003eStep 6: Freeze samples at -20°C or below for storage beyond 48 hours.\u003cbr\u003eStep 7: Never freeze whole blood — always separate serum from cells first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Mistakes That Compromise Test Results\u003c\/strong\u003e\u003cbr\u003eSeveral recurring mistakes invalidate serum tube samples in real clinical practice every day:\u003c\/p\u003e\n\u003cp\u003eUnderfilling the tube — partial vacuum draws affect clotting and serum yield significantly.\u003cbr\u003eVigorous shaking during inversion — hemolysis ruins many chemistry and hormone tests.\u003cbr\u003eSkipping the 30-minute clot time — incomplete clotting blocks the centrifuge separation step.\u003cbr\u003eCentrifuging too aggressively — excessive g-force breaks fragile glass tubes during processing.\u003cbr\u003eStoring serum on the cells — prolonged contact alters glucose and potassium values.\u003cbr\u003eDrawing out of order — additive carryover from other tube types contaminates serum.\u003cbr\u003eUsing expired tubes — vacuum strength drops past expiration, causing partial fills routinely.\u003cbr\u003eMislabeling tubes — wrong patient identification creates dangerous laboratory errors throughout the workflow.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eGlass vs Plastic Serum Tubes\u003c\/strong\u003e\u003cbr\u003eModern labs choose between glass and plastic serum tubes based on specific testing requirements:\u003cbr\u003eGlass advantages:\u003c\/p\u003e\n\u003cp\u003eChemically inert surface — no leachable plasticizers affecting trace analyses.\u003cbr\u003eBetter optical
