A woman looking to have a baby can go through frustrating times when she discovers on the home pregnancy test a false positive result. Unlike blood pregnancy tests, urine pregnancy tests can display false positive results on account of a number of medications which interfere with the accurate result. Also, incorrect usage of the urine test can lead to false positive or false negative results, too. Claim Your 20 Free Pregnancy Tests – Click Here
The main 6 types of medications that cause false positive pregnancy tests results are as follows.
Given the fact that any pregnancy test displays its results based on accurate measurement of the Human Chorionic Gonadotropin (hCG) hormone level, undergoing treatment with HCG injections causes a false rise in the hCG found in the urine and thus a false positive result.
This medication is frequently prescribed for women trying to conceive, because it helps to induce ovulation when a woman suffers from lack of ovulation or irregular ovulation. Also, it is prescribed after ovulation for boosting the chances of egg implantation.
Anti-anxiety medication and tranquilizers or sedatives also causes a rise in the hCG level and have you believe you are pregnant. Tranquilizers can refer to anxiolytic medication and to antipsychotics. Prescription anti-anxiety medications include benzodiazepines (Diazepam or Valium, Alprazolam or Xanax), azapirones and hydroxyzine. Antipsychotics are prescribed for psychosis management (schizophrenia and bipolar disorder) and include Droperidol, Chlorpromazine, Clozapine, Triflupromazine, Thioridazine.
Anticonvulsants or antiepileptic drugs such as barbiturates (Phenobarbital), benzodiazepines, bromides, fatty acids (valproic acid), fructose derivatives, GABA analogs, Primidone and triazines can also cause false positive tests.
Anti-Parkinson medications also determine a rise of the hCG level in urine. These include Phenylalanine, Tyrosine, dopamine increasing drugs like Bromocriptine and anticholinergics like Benzatropine and Scopolamine.
Some prescribed diuretics, used to increase the urine output can also lead to false results. These include loop diuretics like Furosemide, spironolactone, thiazides and osmotic diuretics like mannitol and glucose.
Promethazine, a drug used to treat allergies, motion sickness, and vomiting and which has a powerful sedative effect, can also create misleading test results as well.
All these abovementioned medications that cause false positive pregnancy tests determine an increased level of the Human Chorionic Gonadotropin hormone in the urine, thus misleading a woman into believing she is pregnant. Prior to taking the home pregnancy test, it is advisable to avoid these medications altogether so as to prevent false positive results. For more accurate results, blood pregnancy test kits are recommended.
