The order of draw is the sequence in which blood collection tubes are filled during venipuncture.

• The order of draw is important to prevent cross-contamination and ensure accurate test results.

• The most common order of draw is as follows: blood culture tubes, coagulation tubes (sodium citrate), serum tubes, heparin tubes, EDTA tubes, and glycolytic inhibitor tubes.

• Sodium citrate tubes are used for coagulation tests, such as prothrombin time (PT) and activated partial thrombopla...read more

EDTA stands for Ethylenediaminetetraacetic acid. Swabs typically contain 70% isopropyl alcohol.

• EDTA full form is Ethylenediaminetetraacetic acid

• Swabs usually contain 70% isopropyl alcohol

The tube carbamazepine test is used to measure the level of carbamazepine in a patient's blood.

• The test involves collecting a blood sample from the patient.

• The blood sample is then placed in a tube containing a reagent that reacts with carbamazepine.

• The tube is then placed in a spectrophotometer to measure the absorbance of the reaction.

• The absorbance reading is compared to a standard curve to determine the concentration of carbamazepine in the blood.

Heparin tubes are used to collect blood samples for coagulation testing.

• Heparin tubes contain lithium or sodium heparin to prevent blood clotting.

• Mix the blood gently with the anticoagulant in the tube by inverting it several times.

• Use a syringe to draw blood directly into the tube, ensuring proper mixing.

• Label the tube with patient information and send it to the lab for testing.

• Heparin tubes are commonly used for tests like PT, APTT, and fibrinogen levels.

ESR full form is Erythrocyte Sedimentation Rate.

• ESR is a test that measures how quickly red blood cells settle at the bottom of a test tube.

• It is a non-specific test used to detect inflammation in the body.

• High ESR levels can indicate conditions like infections, autoimmune diseases, and cancer.

Blood culture test involves collecting blood samples and incubating them to check for bacterial growth.

• Collect blood samples from the patient using a sterile technique

• Inoculate the blood samples into culture bottles containing growth media

• Incubate the culture bottles at the appropriate temperature for a specific period of time

• Check for bacterial growth by observing turbidity or using automated systems

• Subculture positive samples to identify the specific bacteria causing the in...read more

Sodium fluoride tubes are used to collect blood samples for glucose testing.

• Collect blood sample using a sodium fluoride tube

• Mix the sample gently to prevent clotting

• Store the tube in a cool place until testing

• Commonly used for glucose testing in diabetic patients

Fasting sugar average is a measure of blood glucose levels after fasting for a certain period of time.

• Fasting sugar average is used to diagnose and monitor diabetes.

• It is typically measured after an overnight fast of 8-12 hours.

• Normal fasting sugar average is usually between 70-99 mg/dL.

• Higher levels may indicate prediabetes or diabetes.

• Lower levels may indicate hypoglycemia or other medical conditions.
