Everything to Know about Pregnancy Test Results
Recognizing the early symptoms of pregnancy—such as missed periods, nausea, fatigue, frequent urination, and breast tenderness—can prompt you to take a home pregnancy test. These tests are designed to detect the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy, in your urine. While home pregnancy tests are widely available and easy to use, their accuracy hinges on several factors, including the sensitivity of the test, how closely you follow the instructions, and when you take it. The most reliable time to assess your pregnancy test results is about one week after your missed period. This timing allows hCG levels to rise sufficiently for detection.
Testing too early may lead to a false negative, as there might not be enough hCG in your urine yet. For individuals with irregular cycles or uncertain period dates, waiting at least 21 days after unprotected intercourse can also yield accurate pregnancy test results. By following these guidelines, you can increase the likelihood of obtaining reliable results from your home pregnancy test.
When interpreting your pregnancy test results, it’s crucial to read them within the timeframe specified in the instructions—typically within 3–5 minutes—to avoid confusing evaporation lines with positive indicators. A positive result is usually indicated by two lines or a plus symbol (depending on the brand), while a single line or minus symbol typically means negative. If you see a faint second line, it could still indicate a positive result due to lower hCG levels early in pregnancy; retesting after a few days can help clarify the situation.
While most home tests boast up to 99% accuracy when used correctly and at the right time, certain factors can affect the reliability of your pregnancy test results. These factors include expired or improperly stored tests, diluted urine from excessive fluid intake before testing, and certain medications or medical conditions. If you receive conflicting results from multiple tests or if your period does not start even after negative results, it’s advisable to consult with a healthcare provider for confirmation through blood tests or an ultrasound. Understanding how and when to use pregnancy tests—and how to interpret their results—empowers you to make informed decisions about your reproductive health.

Different pregnancy tests
The accuracy of your pregnancy test depends on the type of test you are taking. Here are some of the options:
Home pregnancy tests
The home pregnancy tests are sensitive enough. You can use these tests on your first missed period day. This pregnancy test strip determines whether you are pregnant by detecting hCG in your urine, which is a hormone only present in a pregnant woman’s body. If you get a negative test result, the strip changes color when detecting this hormone. You should wait about 10 minutes for the most accurate result. There are a few tips you can use to follow in order to receive a more accurate pregnancy test result at home:
- Use first-morning urine. Taking your test with your first urination of the day is a helpful trick. Your urine usually carries more hCG in the morning, therefore, your results may be more accurate
- Hold the strip in contact with your urine for 5-10 seconds.
- Wait 5-10 minutes before reading the results, especially to avoid any confusion with an evaporation line.
- Read and follow the instructions in your pregnancy test kit carefully
Taking these tests twice is the best idea to ensure their accuracy. You can buy a pregnancy test kit from pharmacies and even supermarkets, depending on where you live. Sexual healthcare services usually provide free test kits.
Urine tests
You can get a urine pregnancy test clinically, at a medical center, or your doctor’s office. These urine pregnancy tests are not always more accurate than home tests, but since you take them under the control of your doctor, it is less likely for any errors to appear in the process to lower your test’s accuracy. It’s important to check the expiration date of the urine pregnancy test. There are no risks involved with this test. In rare cases, this test detects non-pregnancy-related issues, which your doctor will look into. Most times, you will receive your results within one week, but this varies from clinic to clinic.
Blood tests
A pregnancy blood test is also a clinical test you can take in your doctor’s office or in a medical center. This test aims to detect the hCG in your blood. This hormone displays whether you are pregnant or not. Depending on the type of blood test you are taking, you will receive different information.
Qualitative blood tests
These tests show either a yes or a no. You do not get any more details from them. They are easy to use and quick. Many people use these tests at home. They help you know if you might be pregnant. The results are clear and simple to read.
Quantitative blood tests
These tests do more than just tell you if you are pregnant. They also check the hCG in your blood. This means they measure a hormone called hCG. This hormone is found when you are pregnant. So, the test tells you both if you are pregnant and how much hCG is in your body.
How accurate is your home pregnancy test result?
The accuracy of HPCs depends on how carefully you follow the instructions. The inaccuracy is usually regarding the negative result, and a positive result is usually certain. In case of not following the instructions correctly, or taking the test too early, your results may not be as reliable. If you receive a negative result, but still experience pregnancy symptoms, it’s a good idea to take another test a few days later. Consulting a doctor may also be helpful.
How soon will a pregnancy test show positive?
Qualitative blood tests are a reliable method for confirming early pregnancy status. They detect the presence of human chorionic gonadotropin (hCG), a hormone produced shortly after the fertilized egg implants itself into the uterine lining. Typically, these tests provide a yes or no answer regarding pregnancy and are beneficial for individuals who may experience low levels of hCG, which could result in a false negative on a home pregnancy test. This makes them valuable for accurate prenatal care planning.
How long does it take to get results of a pregnancy test?
Qualitative blood tests offer a straightforward method to determine pregnancy by detecting the presence of human chorionic gonadotropin (hCG) in the bloodstream. This test confirms whether or not the pregnancy hormone is present, typically providing results within a few hours. Considered more sensitive than urine tests, qualitative blood tests can show positive pregnancy test results earlier, making them beneficial for pregnant women seeking immediate confirmation. However, understanding the pregnancy test results is crucial, as a faint line could indicate a lower level of hCG or an early pregnancy. There are also different types of pregnancy tests available for those seeking alternative options.
How common are false results on pregnancy tests?
Qualitative blood tests offer a crucial advantage when assessing pregnancy status. Unlike home urine tests, these blood tests detect the presence of the pregnancy hormone, human chorionic gonadotropin (hCG), with a higher degree of sensitivity. They can confirm pregnancy even at very low levels of hCG, allowing for early detection prior to a missed period. These tests accurately measure the level of hCG, ensuring that accurate test results are essential for timely prenatal care, addressing any early pregnancy symptoms appropriately for the health of both the mother and the developing fetus.
When should you take a pregnancy test?
Taking a pregnancy test should ideally occur after a missed period for the most accurate pregnancy test results. Most home pregnancy tests recommend waiting until the first day following your missed period, as this allows the pregnancy hormone, hCG, to reach detectable levels in urine. However, for those eager to know earlier, testing a few days before the expected period may yield results, though they might be less reliable. Following test instructions and using the first morning urine can enhance the accuracy of your pregnancy test results. It is also important to remember that testing should ideally be done on the first day of your missed period for the best reliability.
What time of day is best to take a pregnancy test?
Qualitative blood tests provide a straightforward approach to determining pregnancy status among the main types of pregnancy tests. Typically performed at a healthcare provider’s office, these tests detect the presence of human chorionic gonadotropin (hCG) in the blood, allowing for an early and accurate result. While they can confirm pregnancy, timing is crucial for the best outcome, especially immediately following a missed period. Understanding these tests helps distinguish between normal and abnormal pregnancy signs, ensuring timely prenatal care when necessary for positive pregnancy test results.
How to interpret pregnancy test results
Interpreting the outcome of a pregnancy test requires attention to detail. The presence of two distinct lines typically indicates a positive result, signaling the production of the pregnancy hormone hCG. However, irregularities such as a faint line may suggest early pregnancy or lower hCG levels. A single line indicating a negative result could be valid even in cases of a missed period. Familiarity with the test kit’s instructions is essential to ensure the accuracy of results, including the expiration date.
What are C and T in a pregnancy test?
Qualitative blood tests, also referred to as serum pregnancy tests, are designed to detect the presence of human chorionic gonadotropin (hCG) in the bloodstream. These tests provide a straightforward positive or negative result, indicating whether a fertilized egg implants in the uterine lining. Unlike home pregnancy tests, qualitative blood tests can offer confirmation of early pregnancy as they are capable of identifying lower levels of hCG. Understanding these pregnancy test results can assist pregnant women in making informed decisions about their healthcare and prenatal care, ultimately leading to a healthier pregnancy journey through the interpretation of accurate pregnancy test results.
What to do when a pregnancy test is positive?
This step depends on whether or not you were planning to get pregnant. If you receive positive results while planning for a baby, take one or two more tests just to ensure accuracy. After that, you can visit a doctor. Make sure to see a doctor before the 2-month mark. Your doctor will instruct you on the further actions to be taken and may suggest a pregnancy due date calculator to help you understand your timeline. The changes you need to adapt your life to may vary. However, if you were not expecting a baby, you have a few options on hand:
- Abortion
- Continuing the pregnancy and carrying it for adoption
- Planning to keep the baby
Most clinics and healthcare centers provide help, guidance, and support as well.
Negative pregnancy test result
If you receive negative results and wanted a baby, you can keep trying to get pregnant. You can seek advice from a doctor if you fail to become pregnant after one year of trying. Getting a fertility test may also be beneficial. If you or your partner have any infertility issues, you can start considering infertility treatments as well. Some popular infertility treatments include IVF and surrogacy. Still, if you were not planning to become pregnant and received negative results, you might want to take another test a bit after, just to make sure. If you keep experiencing pregnancy symptoms even after receiving negative results, you might want to see a doctor.
Why is my pregnancy test negative but I don’t have a period?
Qualitative blood tests are essential for understanding pregnancy status and detecting the presence of human chorionic gonadotropin (HCG or sometimes hCG) in the bloodstream. These tests provide a binary result indicating whether human chorionic gonadotropin is present, confirming pregnancy, or not detectable for a negative result. They are often more sensitive than urine tests, offering reliable data within a shorter timeframe. For those questioning early signs of pregnancy, these tests can clarify hCG levels and help guide the next steps in prenatal care according to the patient’s unique situation.

Do medications affect your pregnancy test result?
Most medications do not affect your results, including the situation of an ectopic pregnancy. Antibiotics, alcohol, and even birth control usually do not change your results. The only group of meds that may affect and shift your results are fertility drugs. For example, if you are taking tranquilizers or anticonvulsants, you may receive a false negative result. In case of taking these drugs, make sure you share your results with a doctor to ensure their accuracy.
Will an ectopic pregnancy show up on a pregnancy test?
An ectopic pregnancy typically produces hCG, the pregnancy hormone, and can show up on a pregnancy test. However, the levels of hCG may be lower than in a normal pregnancy, potentially leading to a false negative result. Women experiencing early signs of pregnancy and signs of an ectopic pregnancy, such as abdominal pain or unusual bleeding, should consult their healthcare provider immediately. Regular monitoring of hCG levels through blood tests can help ascertain pregnancy status and detect any complications early.
The Bottom Line
There are a couple of different pregnancy test methods for figuring out whether you are pregnant or not. From home kits and tests you can take yourself, to clinical urination tests and blood tests, your pregnancy test results mostly depend on how early you take the test and how well you follow the instructions. Most HPTs are reliable if you follow the instructions carefully. However, since medical tests take place under a doctor’s control, the inaccuracy risks are lower. After receiving your pregnancy test results and making sure they are accurate, you can decide your next steps with careful trip considerations.
