Pregnancy Test Answers
hCG is human chorionic gonadotropin. It is a hormone produced by the placenta during pregnancy. Home pregnancy tests (HPTs) are designed to detect it.
Basically, the pregnancy tests that detect the lowest number of units should give you the earliest results.
Home pregnancy tests (HPTs) are designed to detect hCG, a hormone released by the placenta right after the embryo begins implanting into the uterine lining. The hormone is released in a pregnant woman’s urine.
You may be able to get a positive HPT about 10 days after ovulation. If you have not had an hCG injection (common in infertility treatment, brands include Profasi and Pregnyl), you believe the positive, but you might get a false negative. If your period is late, test again. Your hCG levels should double every 2-3 days and many people won’t have a positive HPT until the first day of a missed period or even a few days later.
You should use midstream urine — meaning you should pee a little first and then either hold the test stick in your urine stream or use a collection cup. If you would like to collect urine in a cup even though you bought a stick test, you need to hold the absorbent tip of the stick in the cup of urine for 10-15 seconds. Otherwise, follow the directions with the test.
That depends how long after ovulation you are testing. If you are testing early, a four-hour wait is a good idea. The more hCG you have in your system, the less long you’ll need to hold before trying to test.
You can, but you should wait 7-14 days after your last injection before the shot is out of your system. If you test too soon, you might get a false positive. Wait 14 days after a 10,000 IU injection, 10 days after a 5,000 IU injection, or 7 days after a 2,500 IU injection.
An average would be about 25 mIU at 10 dpo, 50 at 12 dpo, 100 at 14 dpo. Please consult http://www.advancedfertility.com/earlypre.htm or http://www.inciid.org/betas.html for charts on hCG levels in early pregnancy.
You may be pregnant and just didn’t have a high enough level of hCG to trigger the test within the usual time frame. However, it also could be the way that test reacts over time, so you really need to test again either way in order to be sure of the result. Some brands indicate that an “evaporation line” will appear if the test is left to sit (Equate, for example). Generally speaking, you should not rely on any positive result that does not show up within the time limit stated in the test instructions.
A blood test is more accurate, but not necessarily more sensitive. A lot depends on the lab. A quantitative blood test, usually called a beta hCG test, measures the exact units of hCG in the blood. That means it will detect even the most minimal level. There is another type of blood test sometimes called a qualitative hCG. This is a test that simply gives a yes or no answer to whether you are pregnant. Just like urine tests, labs vary as to what is considered a positive pregnancy test. Common cutoffs for positive are 5, 10, and 25 units. A level under 5 is considered negative. A test that is only triggered at 25 units of hCG is not any more sensitive than several of the urine HPTs.
No. You may get a darker line as your pregnancy progresses, but the HPT is not accurate enough to give you a full picture. Only a quantitative beta hCG blood test can tell you this. Best to have the blood tests performed at the same lab since standards vary.
It doesn’t necessarily mean something is wrong, but it warrants further exploration including an early ultrasound (6 weeks LMP). Slow-rising hCG can be related to impending miscarriage or ectopic pregnancy. One important thing to remember is that on average hCG levels double approximately every two days from 4-6 weeks LMP, then doubles every 3 days when the level is 1600-6000, then the doubling slows to every 4 days or so. Levels peak a week or two before end of the first trimester (14 weeks LMP) before declining in the second trimester.
Many doctors will do two or three hCG levels to confirm doubling and stop there. Most others will stop after a fetal heartbeat is detected since hCG levels vary greatly and doubling begins slowing down. After a heartbeat is seen or heard, the chance of miscarriage drops to 16% before 6 weeks LMP, 5% from 7-9 weeks, 1-2% after 11 weeks (reference).
The only way to know for sure is to get a quantitative hCG blood test run. If you were pregnant but are miscarrying early, you may still have some level of hCG on the first day of bleeding — but you need to go for the test as soon as possible. It is also possible that you got a false positive on the pregnancy test, in which case you should call the manufacturer with the lot number and try to get your money back.
It may be that the qualitative blood test is less sensitive than the home pregnancy test, so it would be a good idea to get a quantitative hCG (measures the actual hCG level).
Yes. Most of the tests can detect lower levels of hCG than what is listed in this FAQ, but the levels printed here are the ones quoted from the manufacturers.
Yes. Most women will register on HPTs by the time they are a few days late for a period, but not everyone will. If you suspect you are pregnant, you should see your doctor for a quantitative hCG test no matter what result you get from an HPT.
UTI Test Strip Answers
Symptoms of a Urinary Tract Infection include burning or pain during urination, frequent urination, fever, back or groin pain, exhaustion, chills, nausea and vomiting; urine may appear to be cloudy, milky, or reddish if blood is present.
Urinary Tract Infections are detected by checking for the presence of nitrites and leukocytes in the urine.
A Urinary Tract Infection occurs when bacteria multiplies. If the infection is not treated promptly, serious damage can affect the kidneys. Common causes of UTI are from the use of catheters, sexual intercourse, diabetes, insufficient fluid intake, or pregnancy. For persons who have kidney stones or enlarged prostate glands, chances are higher that they will contract a urinary tract infection.
Yes, this is possible; however, it is more common in young children, pregnant woman and the elderly.
In most cases, NO. It is important to make sure that your genital area is clean before taking the test. In some cases, a false positive will result if the genital area hasn’t been cleansed thoroughly, there is vaginal discharge or menstrual blood in the urine; or there is an inflammation of the urinary tract.
Yes, New Choice UTI strips are accurate. They are the same strips that are used in clinics and doctor’s offices. These tests are lab tested for advanced quality assurance.
You can test any time of day; however, your first morning urine is recommended for best results. Avoid testing during menstrual period.
Most substances will not interfere with the test. Consult your physician if you are taking antibiotics. Some medications can affect the color of your urine causing false negative results as well as large quantities of Vitamin C.

Personal Lubricant Answers
Personal lubricants can be useful during sexual activity after menopause or if the female is experiencing diminished natural lubrication. Consequently, sex can become painful. Some of the factors that can contribute to vaginal dryness are dips of Estrogen levels during menopause, emotional factors and some medications. Lubricant also makes it easier to use condoms, a must for protecting against sexually transmitted diseases. Lubricants can help ease vaginal dryness and improve intercourse.
Experts are of the opinion that water-based lubricants are the safest lubricants for use since they do not cause latex to deteriorate, and should not irritate the skin. Additionally, water-based lubricants rinse off easily in plain water. Our line of feminine hygiene products includes a variety of water-based lubricants and vaginal moisturizers.
Marijuana Drug Test Answers
When the marijuana drug test, such as the NEW CHOICE At Home Marijuana Drug Test Strip, is properly used with the urine sample, the urine specimen migrates up the card by capillary action. If THC is not present at a great enough level in the urine sample, it will not be able to prevent its antibody on the marijuana drug test card from reacting with the drug-protein conjugate on the test card. When this reaction occurs, a colored line appears in the Test Region and the result is Negative. When marijuana is detectable in the urine it prevents the antibody from reacting with the drug-protein conjugate. Therefore, no colored line appears and the result of the marijuana drug test is Positive.
Most likely not. Generally it takes about 2-5 hours for a drug to show up after consumption.
Laboratory test results for drugs of abuse have indicated a greater than >98% accuracy when used according to the provided directions.
NO! Urine concentrations of THC above the cut-off sensitivity level of the test, or a positive result, is possible only through use/inhalation. However, second hand smoke will be in the system, but not at the concentrations that would indicate drug abuse.
No. The results are not affected by these substances. Urine drug tests are substance and derivative metabolite specific. The commonly taken medications are chemically and structurally different after being metabolized by the body from the drugs being tested for and therefore, under most circumstances, they do not interfere with test results.
NO, the test will not function properly.
This is possible if the test specimen is switched. Also, there are fluid intake adulterants that can neutralize the drug or its metabolite so it shows as absent on the test.
The morning is the best time to take the test. The more water and/or fluids that are drunk throughout the day can dilute the urine.
