Many women depend on the plethora of home gestation tests that are useable these days . These test are easy to do and the manufacturer of these packs claim that their run are 99 % exact . However , enquiry has shown that despite these claims there are around 5 % chances that the mental test may show a imitation convinced test . This signify that the test will show that the female person is pregnant while in actuality this may not be the case . This is according to various research that have been done over the last 10 years.[1 ]
The maker of these trial outfit province that the test done within the first two workweek after assume conception may not show an accurate result since the pregnancy hormones in this time do not get high enough to show a positive outcome . However , according to studies it has been watch that pregnancy tests may also give a imitation overconfident run even at five weeks into the presumed concept when the maternity hormones in actuality should be at their peak.[1 ]
There are many factors that may cause a female to get a false positive result during a home base pregnancy test . This may vary from hormonal change to sure medical consideration or deal certain medications . These causes are what have been excuse in the article below:[2 ]
5 Causes For A False Positive Pregnancy Test
Some of the causa for a female getting false irrefutable pregnancy run are :
Evaporation phone line : To well understand this factor , it is important to understand how a pregnancy test gives the results . It is vital for the female person to register the instructions on the pregnancy kit carefully before using it . unlike pregnancy kits have dissimilar book of instructions which make it important to read all the focal point of habit carefully . In most of the test kits , it will be recommended to read the final result within 5 minutes of using the outfit and the maximum time terminus ad quem of reading the result is 10 minutes . A non - digital test kit will show a single line if the female is not significant and two line if she is.[2 ]
In case the test termination is read after the maximal time limit , it may give a sham positive upshot since the urine will leave behind an evaporation rail line which will be like to the line that will indicate a positive pregnancy trial . This often at fourth dimension will go the female person to believe that she is pregnant when in fact she is not.[2 ]
Previous History of Miscarriage / Abortion : If a female has had an abortion or amiscarriageand hindrance for pregnancy a short time afterwards then again the tryout will be a false cocksure . This is because even after spontaneous abortion or miscarriage the pregnancy internal secretion will still be high-pitched in the organic structure cause the result to be defective . Once a female conceives the body starts secreting beta hCG which is the gestation endocrine and its level go to rise . However , after a miscarriage or an abortion this degree start out to go down but only very slowly.[2 ]
Thus if a gestation psychometric test is carry out a short meter after the consequence it may often go to false incontrovertible gestation tests . It takes anywhere from a hebdomad to about a calendar month for the pregnancy internal secretion levels to put down down to normal . If a test is lead within this time frame , then it will almost always buckle under a false confirming result.[2 ]
In some case , the miscarriage is only fond in that there are some tissues left behind from the gestation in the womb which will continue to release pregnancy hormones make fictitious positive pregnancy tests . Thus after a miscarriage a dilatation and curettage is done to remove the womb of any junk remain from the pregnancy.[2 ]
Molar Pregnancy : This is yet another cause for a female to have a put on positive maternity psychometric test . This status results due to genetic abnormality during the time of invention resulting in the pregnancy turn unnatural . Molar pregnancy can be fond or thoroughgoing . In a staring molar pregnancy there is terminated absence seizure of the chromosomes of the female and only male chromosome are present . This contribute to consummate absence of the development of fertilized egg or placenta.[2 ]
In a fond molar pregnancy , the female will have placenta and embryo . However , instead of one set of chromosome from the male and one set of chromosome of female person , the embryo will have two sets from the male and just one set from the distaff causing genetic irregularity . It cause unnatural growth of the conceptus and placental tissue . This also leads to the female get a fictive positive pregnancy test . This condition necessitate dilation and curettage for complete cleaning of the uterus.[2 ]
It is vital for the beta hCG levels of the female with molar pregnancy be monitor after the procedure to ascertain that they return back to the normal level . At times , the embryo and the placental tissues from a molar pregnancy continue to uprise . This is medical referred to as trophoblastic disease and is an emergent aesculapian condition . This will demand surgery to completely move out the uterus.[2 ]
medication : In some cases , taking certain medications can also result in a female experience a faux overconfident pregnancy examination . These medications generally have Beta hCG as one of their ingredients . The medications are normally given for treating sterility . The medication cause the levels of this pregnancy hormone to originate up result in a false positive gestation mental test . It should be take down however that medications for other conditions do not move the results of a maternity test.[2 ]
Medical Conditions : There are also sure medical conditions that can result in a pretended overconfident pregnancy trial . Conditions where the pituitary secreter is affected may result in significant raise in beta hCG storey ensue in a female having a false overconfident pregnancy test . This is normally insure in perimenopausal and menopausal female . sealed manikin of Crab that move the ovary , liver , kidney , or lung also may lead to significant hike in beta hCG level causing false confirming gestation tests.[2 ]
In female person who have a history of ovarian cysts there may be a significant rise of the pregnancy endocrine stimulate her to have a false positive pregnancy tests . female with frequentUTIsor nephritic dysfunction also tend to have in high spirits beta hCG levels.[2 ]
In decision , as stated by the United States ’ post for Women Health home gestation mental testing kit give 99 % precise resolution if they are done properly fit in to the instructions provided on the recording label . However , various studies have conclude that there may be a discrepancy of about 5 % where the results may be false positive .
However , if the test is done within the clock time frame specified by the manufacturing business of the tryout kit then the results are mostly precise , especially if they are done after missing a period.[1,2 ]
Studies suggest that taking a test forthwith after conception may not give the right result since it take meter for the beta hCG levels to rise . In some case , it has been show that false positive termination are observed even at five weeks where the trial run solvent are false positivistic . It may be due to various factors that impact the results if a pregnancy rest.[1,2 ]
If a female has a history of stillbirth or abortion then the level of beta hCG may be high for some time after the event . Thus if a test is conducted during this time then it will soften a false prescribed resultant . likewise female person with a history of ectopic maternity or a molar maternity will also have high layer of beta hCG and will have a false positive pregnancy trial run results.[1,2 ]
Proper treatment of these medical conditions is required will distension and curettement to increase the chances of the distaff getting pregnant again . Additionally , conducting the pregnancy exam according to the instructions is a must to avoid getting simulated prescribed gestation mental testing results.[1,2 ]
There are also sure medical conditions likeovarian cystsor circumstance that impress or damage the pituitary gland can also affect the levels of beta hCG in the body . This again cause a female person to have a false positive pregnancy test results . People with a history of cancer of the ovaries , kidneys , lung , or liver also be given to have in high spirits stage of beta hCG causing them to have false convinced pregnancy tests . It is essential to rein out these conditions as a contributing component in mass who are at risk of exposure in them having false positive gestation tests.[2 ]
