1. 3ini CHOLESTEROL Reagent strips for the determination of Total Cholesterol concentration To be used only with the 3in1 Instructions for use Introduction With the 3in1 Cholesterol strips it is possible to quickly check cholesterol levels in the blood and inform the family physician to find a suitable therapy or to check up on an existing therapy The level of cholesterol in the blood is influenced by the diet but also by medicines diabetes mellitus pregnancy and severe illnesses It is recommended to check blood cholesterol concentration on all people who are used to smoke to drink too much alcohol and to eat fat and are over weighted or do not exercise enough It is specially recommended to people who already had heart disease or with familial cases of heart diseases before the age of 60 Perform the test at fast for at least 9 hours Test principle The test is based on a Cholesterol Esterase Oxidase Peroxidase Chromogen reaction The intensity the colour developed from the reaction is proportional to the concentration of Total cholesterol in the blood Composition The reactive area of each strip contains chromogen min 0 025 mg Cholesterol Esterase 0 8 IU Procedure e Open the pack of 3in1 Cholesterol strips pull out the data chip of green color e Insert the data chip into the proper space on the side of the meter picture 1 e Open the vial take a strip and immediately close it e Insert the strip in the strip holder of2. Do not use serum or plasma on the strip Limitations e If the value of cholesterol after testing does not correspond to the normal sensations felt by the patient and to the basic knowledge of health conditions and symptoms repeat the test Read the user manual to verify the correct determination procedure and consult your physician e Recent illness pregnancy and hormonal contraceptives may influence the cholesterol values Results obtained under such conditions must be referred to the physician before any dietetic or therapeutic measures are applied e Should the values of cholesterol be over 240 mg dL 6 1 mmol L contact a physician immediately e Reducing agents like for example Ascorbic acid at normal concentrations do not interfere If high quantities are taken low cholesterol values could be obtained e The result is affected by high levels of steroids triglycerides and bilirubin e Inaccurate results can be obtained at high altitudes since the concentration of oxygen is lower e Abnormal values of hematocrit higher than 50 or lower than 35 can influence the results Minimum volume of blood sample 10 uL Accuracy The average error of the 3in1 system compared to the reference method CHOD PAP is lt 10 In a series of measurements performed in a hospital the following linear regression has been obtained y 0 9599 x 5 4277 Precision Repeatability the average inaccuracy is lt 5 in a series of measurements performe
3. the meter picture 2 with the coloured side visible till to hear an acoustic signal bip e Check that CH symbol appears on the display and check that the number on the strip vial label is the same of the one on the display picture 3 e wash the hand with hot water and massage the finger that you choose for the pricking to increase the blood flow Let your arm hang down for about one minute e execute the puncture of the finger using the lancing device and a sterile lancet e remove the first drop with a sterile gauze and gently press the finger to obtain a second drop 10 microliters e approach the pricked finger with the drop of blood to the lower part of the strip picture 4 it is the part that come out of the instrument The sample of blood will be automatically aspirated by the strip Do not remove the finger until the moving segments will appear on the display the instrument will emit an acoustic signal bip e Some seconds the result will be displayed e Use the ejector key on the backside of the meter to remove the used strips in order to avoid contaminations Only one measurement has to be carried out for each finger pricking Carefully follow the instructions contained in the user manual All components of the pack has to be disposed properly avoiding To apply the drop of blood contaminations on the round reactive area Correct test execution check After each measurement check the circular opening
4. under the reactive area in correspondence to the opposite surface where the blood sample has been applied the colour must be uniform If not repeat the measurement Testing the system A check up of the user s skill the correct working of the 3in1 instrument and its strips must be periodically carried out through the use of the 3in1 Cholesterol Control Solutions and by following the included instructions The expected results for this test are printed on the vial s label of the 3in1 Cholesterol strips that are being used Storage and expiry date Keep the reactive strips at temperatures between 5 C 41 F and 30 C 86 F and keep them in the original vial Do not expose to direct sun light Close the vial with the original cap immediately after pull out the strip In this way the strips will last up to 3 months after the first opening The expiry date on the package of strips refers to a new unopened vial The use of expired strips can cause wrong results Do not expose to excessive humidity Do not freeze Table of results Cholesterol below 130 mg dL 3 3 mmol L LO Cholesterol between 130 mg dL 3 3 mmol L and 400 mg dL 10 2 mmol L the numerical result Cholesterol above 400 mg dL 10 2 mmol L the display HI Repeat the test Such results mean that the Cholesterol concentration in the sample is very elevated and it indicates a serious risk Contact a phisycian immediately Cholesterol values Less than 200 m

6. g dL 5 1 mmol L desirable values From 200 mg dL 5 1 mmol L to 239 mg dL 6 1 mmol L high risk factor More than or equal to 240 mg dL 6 1 mmol L high cholesterol The analytical results have to be communicated to the physician The self checking can be useful for the physician in order to formulate a diagnosis Warnings e Long exposure to air and light can alter the results It is recommended to keep the strips in the original vial with the cap at room temperature between 5 and 30 C 41 and 86 F e Avoid exposing to excessive humidity do not freeze e Keep the 3in1 Cholesterol strips away from children e Do not perform any tests bellow 10 C 50 F or above 40 C 104 F e Do not touch reacting strips with polluting agents like for example dirty hands the results could be seriously altered e Use the strip immediately after removing it from the vial e Make sure the vial is properly closed after removing the strip and use its original cap containing drying material Do not place the strips in a different container e The 3in1 Cholesterol strips must be used within and not after the expiry date on the package Once the vial has been opened use the strips within 3 months The reactive area on the strip is white in optimal conditions Do not use the strip if the reactive area has a different colour Notes for doctors and labs To measure the Cholesterol with the 3in1 system it is possible to use fresh capillary blood
