The 5 Best Pregnancy Tests Of 2022
Missing a period is often the first sign that a woman may be pregnant. Sometimes a woman may suspect that she is pregnant even earlier. Symptoms such as headaches, fatigue, and breast tenderness may occur even before your period ends. Waiting to find out can be emotional. These days, many women use pregnancy tests (HPT) first to find out. Your doctor may also examine you.
All pregnancy tests work by detecting a specific hormone in the urine or blood that is only present during pregnancy. It’s called human chorionic gonadotropin (kohr-ee-ON-ihk goh-NAD-uh-TROH-puhn), or hCG. hCG is produced when a fertilized egg implants in the uterus. hCG builds up rapidly in your body every day you are pregnant.
HPTs are cheap, private and easy to use. Most pharmacies sell HPT without a prescription. The price depends on the brand and the number of tests inside the box. They work by detecting hCG in urine. HPTs are very accurate. However, their accuracy depends on many things. They are:
The most important part of using any HPT is to follow the directions exactly as written. Most tests also have toll-free numbers you can call if you have questions about usage or results.

If your HPT says you are pregnant, see your doctor right away. Your doctor may use a more sensitive test along with a pelvic exam to confirm pregnancy. Early pregnancy can help you and your baby stay healthy.
The blood test is done in the doctor’s office. During pregnancy, they can detect hCG earlier than a urine test. A blood test can show whether or not you are pregnant about six to eight days after ovulation. Doctors use two types of blood tests to check pregnancy:

Because this is actually the best way to avoid a false negative result (a negative test for someone who is actually pregnant).
Home pregnancy tests can be used on the first day after the first missed period for women with regular/predictable periods. If your period is irregular, you can take the test 14 days after sex, because you probably cannot determine the exact time of ovulation.
How Soon After Sex Can I Take A Pregnancy Test?
Pregnancy tests detect a hormone called human chorionic gonadotropin (HCG), which is produced early in pregnancy. The production of this hormone begins slowly and increases with the progress of pregnancy. Standard urine pregnancy tests detect HCG levels when they reach 20-50 milliunits per milliliter.
If you take the test too early (before menstruation), the level of HCG may not be enough to detect pregnancy, and this may lead to a negative result, even if you are indeed pregnant.
I advise my patients to wait at least one day after their period ends. If you wait a week after your missed period, the chance of false negative results is very low if you have a normal menstrual cycle.
Home pregnancy tests, both brand and generic, detect the HCG hormone very accurately, and any positive result, even a weak line, can be considered positive. HCG is only produced during pregnancy. Any positive result indicates pregnancy.
When To Take A Pregnancy Test
You do not need a pregnancy serum (blood) test to confirm pregnancy. Both urine and blood detect HCG, although the blood test is more sensitive and can detect HCG at much lower levels than a urine test. In some situations, your doctor may want to do a blood HCG test, but it is usually not necessary to confirm pregnancy.
Although most tests claim to be 99% accurate, the ability of a particular brand to detect HCG at levels below 50 mL may vary. Some brands are better than others at detecting lower HCG levels. Even generic tests will accurately detect pregnancy if your HCG level is above 50 milliliters, which is the detection limit of most tests.
The first cause of a false negative test is performing the test too soon after conception. Also, not following the test instructions exactly may affect your score.
The urine should still be positive, even for women who drink a lot of water. However, urine should not be diluted with water before testing. The best time to do this test is in the morning when you first wake up.
Yes, Pregnancy Tests Expire But You May Still Get An Accurate Reading
If a woman who suspects pregnancy has a negative test result or her cycles are irregular, she should repeat the test in a week.
Medications usually do not interfere with results and do not cause false positives or negatives. Only drugs containing HCG affect the result.
Although home tests can detect pregnancy, they do not provide information about viability. It is important to make an appointment with the doctor to confirm the pregnancy and determine the fetal heart rate by ultrasound (usually between 6 and 10 weeks). If the pregnancy test is positive, your obstetrician-gynecologist can provide information about warning signs of an abnormal or worrisome pregnancy and advise you when to make an appointment to confirm the pregnancy. From confirming pregnancy to monitoring fetal growth and ruling out pregnancy complications, blood and urine tests are essential tools during pregnancy.
However, the various prenatal tests during the trimester of pregnancy vary so much that it is difficult to keep track of their types and purposes.

Usually, the first test a woman does is a home urine pregnancy test. Because it takes several days for the pregnancy hormone, human chorionic gonadotropin (hCG), to be detected in the urine, women are advised to take the test 7 to 10 days after a missed period. The woman also takes a urine pregnancy test in the clinic to confirm pregnancy.
A woman’s urine is usually tested at all or most prenatal visits because it provides important clues about how she is feeling and possible signs of complications. A urine test to determine if:

A pregnancy blood test is even different from a prenatal urine test. They are also used in certain pregnancies or when additional needs arise. They can be divided as follows:
In addition to the urine test, a pregnancy blood test is also suggested to the woman, which detects the presence and amount of hCG to confirm that she is pregnant. Although it can detect pregnancy earlier than a urine test (as early as 11 days after conception), the test is usually performed after a positive urine pregnancy test, mainly due to higher costs.
At the first prenatal visit, the doctor takes a blood sample for a complete test:
Maternal blood serum is the term for a prenatal blood test that is given to women twice during pregnancy to determine the risk of chromosomal abnormalities:
Routine Blood Work: Test Types, Importance, Results
Women who are at risk for chromosomal problems due to age or family history, or who have abnormal maternal blood serum results in the first trimester, may have a non-invasive prenatal test (NIPT) at around 10 weeks. This is a new prenatal blood test that checks the mother’s blood for chromosomal abnormalities in the fetus.
Glucose screening is a simple blood test during pregnancy that is performed between 24 and 28 weeks of pregnancy to assess the risk of developing gestational diabetes.
If the results are abnormal, the woman will have another test, a glucose tolerance test, to determine if she really has gestational diabetes.
In addition to prenatal ultrasound and regular physical examinations, prenatal blood and urine tests are valuable laboratory tests that can provide doctors with important clues about a woman’s health, pregnancy progress, and fetal growth. They are often the first signs of abnormalities that, if detected early, can be effectively managed or treated to prevent further problems. with relatively
