[URL="http://www.earlypregnancytests4u.co.uk"]www.earlypregnancytests4u.co.uk[/URL]\n\nEarly Pregnancy Tests 4U provide two types of dependable early-\ndetection pregnancy tests: the pregnancy test strip and the midstream\npregnancy test. We also provide Ovulation Tests allowing you to\npredict when you ovulate. These also come in both the above types.\nAll\ntests comply both to British standards and American FDA standards.\n\n\nOur tests are upto five times more sensitive than the cheaper\nversions\nsold by high street chemist chains and stores. Thus allowing you to\nfind out if you are pregnant sooner with the pregnancy tests and to\npinpoint your ideal time to conceive with the ovulation tests.\n\n\nOur Pregnancy Test Strips are over 99% accurate, and are capable of\ndetecting human chorionic gonadotropin, or hCG, at levels of just\n10mIU/ml/hCG. That means you can begin testing accurately just 6 to 8\ndays after conceiving.\n\n\nUltra Sensitive 10mIU Fastest Pregnancy strip test - CE Marked 0123\nINTENDED USE:\n\n\nFASTEST One Step HCG Urine Pregnancy Test measures the presence of\nthe\nhormone Human Chorionic Gonadotrophin (HCG) in your urine for the\nearly detection of pregnancy.\n\n\nSUMMARY AND EXPLANATION:\n\n\nHCG is produced by the placenta during pregnancy, shortly after the\nembryo attaches to the uterine lining. Usually HCG can be detected by\na home pregnancy test 7-10 days after conception. The further in to\nthe pregnancy you are the higher the levels of HCG in your urine.This\npregnancy dip strip detects HCG in urine at a concentration of 10mIU/\nml (MilliInternational Units) or greater. The concentration of HCG in\nnon-pregnant women is normally 5.0mIU/ml. At the time of the last\nmissed menstrual period, urine HCG levels are about 100mlU/ml with\npeak levels of 100,000 to 200,000mlU/ml seen at the end of the first\ntrimester\n\n\nCONTENTS:\n\n\nEach pouch contains:\n\n\n1. One Step HCG Urine Pregnancy Strip Test\n\n\n2. Desiccant (Discard - Do not eat)\n\n\nSTORAGE AND STABILITY:\n\n\nThe test kit can be stored at room temperature (4 °C to 30 °C) in the\nsealed pouch to the date of expiration. The test kits should be kept\naway from direct sunlight, moisture and heat.\n\n\nPRECAUTIONS:\n\n\nFOR IN -VITRO DIAGNOSITC USE ONLY\nRead directions for use carefully before performing this test.\nDo not use beyond the expiration date on the foil pouch.\nEach test strip can only be used once, do not re-use the test strips.\nDiscard each test after use.\nDo not use if the foil pouch is damaged or has been opened.\nHold the test strip by the handle only.\nOnce the foil pouch has been opened, the test should be used\nimmediately.\ntreat urine samples and used test devices as if they are potentially\ninfectious. Avoid contact with skin.\nTEST PROCEDURE:\n\n\n1. WHEN CAN I CARRY OUT THE TEST?\n\n\nYou can take this pregnancy test from the first day after a missed\nperiod and onwards.\n\n\n2. SPECIMEN COLLECTION AND HANDLING\n\n\nA urine specimen must be collected in a clean and dry container. The\nfirst morning urine specimen is preferred since it generally contains\nthe highest concentration of HCG; however, urine specimens collected\nat any time of the day may be used.\n3. TO CARRY OUT TEST\n\n\nBring the test pouch and urine to room temperature. To begin testing,\nopen the sealed pouch and remove the strip.\nPlace the test strip vertically (straight) into the urine sample,\nmake\nsure the arrows are pointing down. Do not allow the urine level to go\nabove the MAX (maximum) level line (marked by arrows) on the test\nstrip.\nRemove the strip from the urine after 10 seconds and lay the strip on\na clean, dry surface.\nWait for coloured bands to appear. Depending on the concentration of\nHCG in the urine specimen, positive results may be observed in as\nshort as 40 seconds. However, to confirm a negative result, the\ncomplete reaction time (5 minutes) is required. Do not read results\nafter 10 minutes.\nDiscard the test after use.\n\n\n4. INTERPRETATION OF RESULTS\n\n\nNegative: If one coloured line appears in the control region on the\ntest strip and there is no line in the test region, then this\nindicates a negative result, no HCG has been detected in the urine.\nThis means you are either not pregnant or you have tested too early.\nIf you are not sure repeat the test in 48 hours.\n\n\nPositive: If two coloured lines appear on the test strip, one in\nthe test region and one in the control region, then this means there\nis a strong possibility that you are pregnant — HCG has been detected\nin your urine. One line may be lighter than the other, they do not\nhave to match and this is still a positive result.\n\n\nInvalid: If a red line appears in the test region but there is no\nvisible line at all in the control region of the strip then the test\nis invalid. If no lines appear anywhere on the test strip then the\ntest is also invalid and should be repeated using another test strip.\n5. QUALITY CONTROL\n\n\nBuilt in Quality Control Features:\n\n\nAfter addition of the urine sample, coloured bands migrate along the\nmembrane at the leading edge of the dye conjugate and are “removed”\nfrom the test strip completely.\n\n\nWhen the test is complete, you will see a pink-purple coloured band\nin\nthe “C” area of the test strip on negative samples and a pink-purple\ncoloured band in the “T” and “C” area on positive samples. The\nappearance of the CONTROL band indicates that the test strip is\nperforming properly and serves as a procedural control.\n\n\nPERFORMANCE CHARACTERISTICS:\n\n\n1. SENSITIVITY\n\n\nOne Step HCG Urine Pregnancy Test will display positive results with\nspecimens containing HCG at the level close to or greater than 10mlU/\nml.\n\n\n2. ACCURACY\n\n\nComparison studies on the One Step HCG Urine Pregnancy Test with a\nlegally marketed device were performed in-house and in a clinical\nreference laboratory. Positive and negative results were compared and\nthe correlation was >99.5%.\n\n\nPRINCIPLE:\n\n\nThe HCG assay is a rapid one-step test, based on an immunochromato\ngraphic technology. A membrane with an absorbent pad overlapping a\nstrip of fiber glass paper that is impregnated with a lyophilized\ncolloidal conjugate of gold particles and monoclonal solid phase\nantibodies to HCG. Other absorbent pads at the end of the assay\nabsorb\nexcess sample fluid. The urine sample is introduced into the device,\nand proceeds through the absorbent pad, then laterally onto a\nchromatographic membrane. As it contacts the membrane, the sample\ndissolves the lyophilized conjugate. In a reactive sample, the HCG\nantigen will attach to the antibodies in the colloidal solution. As\nthe conjugate moves forward on the membrane, anti-HCG monoclonal\nantibody affixed on the test zone (“T”) will bind the HCG-gold\nconjugate complex, forming a pink line (“T”).\nAll samples will cause a pink colored line to appear in the control\nzone (“C”). This line is formed by the binding of the polyclonal\nantibodies (Anti-mouse IgG) affixed onto the control zone to the\nsample-colloidal gold conjugate. Presence of this line indicates that\nthe test has been carried out correctly. In less than 5 minutes,\nlevels of HCG as low as 25mlU/ml can be detected.\n\n\nLIMITATION OF THE PROCEDURE:\n\n\n1. Alcohol may interfere with the test result. It is not recommended\nto use the test after drinking alcohol.\n\n\n2 .Occasionally urine specimens containing less than 10mlU/ml also\nyield positive results.\n\n\n3.If you test too early HCG levels may still be low and so can give a\nnegative result. In this case, another urine specimen should be\nobtained at least 48 hours later and tested.\n\n\n4.HCG levels may remain detectable for several weeks after normal\ndelivery, delivery by caesarean section, spontaneous abortion or\ntherapeutic abortion\n\n\n5.In cases where very high levels of HCG are present (>500,000mlU/ml)\na false negative result can occur due to a “Prozone” effect. If\npregnancy is still suspected, simply dilute specimen 1:1 with\ndeionized water and retest.\n\n\n6.If a urine sample is too dilute (ie: low specific gravity) it may\nnot contain a representative level of HCG. If pregnancy is still\nsuspected, a first morning urine sample should be obtained and\nretested 48 hours later.
