HbA1c and Diabetes
HumaMeter A1cPage 10 HbA1c and Diabetes Diabetes mellitus (commonly : Diabetes): -Diseases in which a person has high blood sugar (=Glucose) -Reasons: Body produces not enough insulin or cells do not respond to the insulin produced. -2 Types: Type 1 diabetes (Insulin-dependent diabetes): Caused by loss of insulin-producing beta cells in pancreas. Usually young people. Type 2 diabetes (Non-insulin dependent diabetes): Results from insulin resistance (cells fail to use insulin properly). Sometimes combined with insulin deficiency. Typically in adults over 40 and overweight patients.
HumaMeter A1cPage 11 HbA1c and Diabetes Causes of Diabetes High Blood PressureHigh blood triglyceride (fat) levelsPoor diet (processed simple carbs and sugars) Sedentary lifestyle Obesity or being overweightIncreasing agePregnancy (gestational diabetes)Pancreatitis
HumaMeter A1cPage 12 HbA1c and Diabetes Signs and Symptoms of Diabetes Excessive thirstFrequent urinationBlurry vision Sedentary lifestyle Tingling or numbness in the hand and feetWounds that dont healExtreme unexplained fatigue
HumaMeter A1cPage 13 HbA1c and Diabetes Blood Glucose level is used for DIABETES Diagnosis & DIABETES Monitoring Diabetes: High blood sugar (=Glucose)
HumaMeter A1cPage 14 HbA1c and Diabetes Functions of Blood: Transport …of oxygen, nutrients, electrolytes, hormones and enzymes throughout the body Regulation … of fluid and electrolyte balance, temperature Protection …against bacteria, viruses, toxins Wound healing …through clotting mechanism
HumaMeter A1cPage 15 HbA1c and Diabetes Components of Blood Red Blood Cells (RBC) or Erythrocytes – ~99% of blood cells RBC contain hemoglobin, an oxygen-carrying protein. Oxygen binds to hemoglobin in lungs and is the transported to the tissues. White blood cells (WBC) or Leukocytes Initiate immune responses, < 1% of blood cells. Platelets (PLT) or Thrombocytes Crucial for blood clotting & wound healing. Plasma Yellow fluid that carries all blood cells; makes up ~55% of blood.
HumaMeter A1cPage 16 HbA1c and Diabetes Hemoglobin and Glucose Glucose rapidly diffuses into RBC by facilitated diffusion. N terminal valine of hemoglobin alpha chain is available for irreversible glycation: Hemoglobin Hb HbA1c Hb glycation level (= HbA1c level) is proportional to glucose concentration in plasma !
HumaMeter A1cPage 17 HbA1c and Diabetes WHY HbA1c? RBC lifespan: 8-12 weeks HbA1c concentration indicates average blood glucose level over previous 8-12 weeks HbA1c testing - one of the best ways to ensure good diabetes control as it reports an overall level, not a snap-shot concentration HbA1c is not the same as a glucose measurement! Note: A patients HbA1c level is affected e.g. by RBC lifespan, which may be decreased in some conditions.
Summary HbA1c principle - RBC Red blood cells, Hemoglobin & Glucose RBC: Uptake, transport and release of oxygen Oxygen bound to Hemoglobin Hb Glucose easily moves between blood & RBC Irreversible Glycation (=binding of Glucose) of Hb Glycated Hb - HbA1c Level of Glycation ~ Glucose in plasma RBC lifespan = 8-12 weeks: HbA1c concentration indicates average blood glucose levels last 8-12 weeks HbA1c reports an overall glucose concentration, not only a snap-shot concentration! HbA1c testing - the best way to ensure good diabetes Discovery & Control!
HumaMeter A1cPage 19 HbA1c and Diabetes HbA1c LEVELS Commonly used clinical ranges for glycated hemoglobin (HbA1c) are: Normal:< 5.7% Pre-diabetes: 5.7% - 6.4% Diabetic: 6.5% or higher Targets should be set for each individual, taking into consideration their risk of severe hyperglycaemia, cardiovascular status and co- morbidities. Note: The American Diabetes Association recommends a goal of less than 7% DCCT (53 mmol/mol IFCC) for effective management of diabetes and to minimize long-term diabetic complications.
Performing a Test
HumaMeter A1cPage 21 Performing a Test A Few Easy Steps … plus fool-proof display-guidance Scan lot calibration, remove cartridge foil and insert into analyser. Press reagent bead into the cartridge. Close lid. Results in 4 minutes. Take blood sample. Insert into cartridge and snap the stick.
HumaMeter A1cPage 22 Performing a Test Set Up Make sure a tray of cartridges & the analyser are equilibrated to working temperature (room temperature) Scan lot calibration barcode Remove foil lid from cartridge Place cartridge into analyser When prompted, press reagent bead into the cartridge with blunt end of the sample stick
HumaMeter A1cPage 23 Performing a Test Preparing to Take a Blood Sample 1.Make sure your patient sits comfortably. 2.There should be good blood circulation in the hand from which the sample is to be taken. 3.The hand should be warm and relaxed. If in doubt, warm the hand in lukewarm water.
HumaMeter A1cPage 24 Performing a Test Stimulating Blood Circulation 1.Lightly massage the fingers in order to stimulate the circulation. 2.Operator should wear protective gloves. 3.Middle or ring finger should be used for taking a sample. Patient should not wear a ring on the finger used for sampling. 4.Disinfect the puncture site and allow it to dry completely.
HumaMeter A1cPage 25 Performing a Test Lancing the Finger 1.Lance the finger on the side of the fingertip. This is less painful and the blood flow is better. 2.Press lightly on the fingertip and puncture it with a lancet. 3.A lancet that will create a blood flow of μl is recommended. 4.Blot away the first drop of blood. 5.If necessary, press the finger gently again to get a second drop of blood which is large enough to fill the capillary. 6.Avoid milking the finger for blood.
HumaMeter A1cPage 26 Performing a Test Filling the Sample Stick 1.Hold the sample stick with the blood collector and lightly touch the pointed tip on the surface of the blood droplet. 2.Hold the stick in this position until it is filled completely with blood. 3.Check that the blood collector cavity is completely filled and is free of air bubbles. 4.Do not top-up the blood collector if it does not completely fill with blood. Instead, repeat the process with a fresh blood sample and stick.
HumaMeter A1cPage 27 Performing a Test Calibration Lot calibration is performed by scanning in the bar-code label found on of each cartridge box Lot calibration can be done: When the analyser is idle When the analyser requests it = When Scan Lot Barcode appears on the screen
HumaMeter A1cPage 28 Performing a Test Calibration (Cont.) Each reagent lot is directly calibrated to IFCC standards received from the European Reference Laboratory. Cartridge lot calibration is entered into the instrument by scanning the bar code on the box of reagents. Once the test is finished the results will be expressed in: % HbA1c/total Hb traceable to DCCT mmol/mol traceable to the IFCC standard Reporting methods JDS, Mono-S and eAG also can be selected from set-up menu
HumaMeter A1cPage 29 Performing a Test Measuring Procedure 1.Insert the blood collector end of the sample stick into the cartridge that is in the analyser. 2.Snap off the sample stick handle. 3.Close the lid of the analyser. 4.The result will appear on the screen within ~4 minutes.
HumaMeter A1cPage 31 Basic Maintenance Cleaning Procedure Clean the analyser with a non-abrasive lint free cloth. Use a mild detergent or commercially available disinfectant if necessary. Always turn off the analyser by unplugging the power supply before performing any cleaning operation.
HumaMeter A1cPage 32 Basic Maintenance Storage Turn off the analyser on a weekly basis for a minimum of 10 seconds so that when it is turned back on again, it will perform the internal self-checks. If the instrument is stored when not in use, ensure that the mains cord is not liable to damage or kinking. The analyser is calibrated by the manufacturer and there are no user-serviceable parts. Reagent shelf-life of up to 90 days (un-refrigerated). Total Reagent stability of 12 months at 2-8 °C.
