Overview
A pregnancy test is a simple test that checks for a hormone called human chorionic gonadotropin (hCG) in your urine or blood. This hormone is made by the body only during pregnancy, starting soon after a fertilized egg attaches to the womb. The test can tell you whether you are pregnant, usually from the day your period would have been due.
Key facts
Pregnancy tests work by detecting the hormone hCG, which rises quickly in early pregnancy.
Most home urine tests are over 99% accurate if used correctly and after a missed period.
A positive result means you are almost certainly pregnant; a negative result means you are probably not, but false negatives can happen if you test too early.
Questions about this article
Blood tests done by a healthcare provider can detect pregnancy earlier than urine tests.
Yes, pregnancy tests are widely used by people of reproductive age around the world, either at home or in clinics.
Anyone who has a uterus and is of childbearing age and suspects they might be pregnant may use a pregnancy test.
Symptoms
Call emergency services immediately if you notice:
Severe abdominal or pelvic pain, especially if one-sided
Heavy bleeding from the vagina, soaking through a pad every hour
Fainting or feeling lightheaded
Shoulder pain or collapse (may be signs of ectopic pregnancy)
See a doctor urgently (same day) if you notice:
⚠Pain or cramping in your lower belly that does not go away
⚠Vaginal bleeding during early pregnancy (even if light)
⚠Fever or chills with any pregnancy symptoms
Common symptoms
Missed period (the most common reason to take a test)
Nausea or vomiting (morning sickness)
Tender or swollen breasts
Fatigue or tiredness
Frequent urination
Causes
Main causes
A pregnancy test becomes positive when the placenta starts producing hCG after a fertilized egg implants in the uterus.
A negative result means hCG levels are too low to detect, which can happen if you are not pregnant or if you tested too early.
Risk factors
Testing before your missed period increases the chance of a false negative.
Drinking too much fluid before the test can dilute your urine and lower hCG levels.
Certain medical conditions (like ovarian tumors) can rarely produce hCG and cause a false positive.
When to see a doctor
See a doctor urgently if:
If you have a positive pregnancy test and severe pain or bleeding (see emergency symptoms)
If you have a negative test but still have pregnancy symptoms and have missed two periods
Book a routine appointment if:
After a positive home test to confirm pregnancy and start prenatal care
If you have irregular periods and are unsure when to test
If you are trying to conceive and have not had a positive test after 6–12 months
Most pregnancy tests are very reliable. If you follow the instructions carefully and test after your missed period, you can trust the result. If in doubt, repeat the test or ask your healthcare provider for a blood test.
Diagnosis
A pregnancy test is the first step to diagnose pregnancy. It can be done at home with a urine test or at a clinic with a blood test. A positive test is followed by a visit to a healthcare provider, who may do a physical exam or ultrasound to confirm and date the pregnancy.
Tests that may be done
Home urine pregnancy test (over-the-counter kit)
Urine test at a doctor's office or clinic
Blood test (quantitative hCG) to measure exact hormone levels
Ultrasound scan (done later to confirm the pregnancy is in the uterus and to check for a heartbeat)
What to expect at your appointment
Taking a home urine test is straightforward: you pee on a stick or into a cup and dip the test. A positive result usually shows two lines, a plus sign, or the word 'pregnant'. A negative result shows one line or 'not pregnant'. Blood tests are done by a healthcare professional and results may take a few hours to a day.
Treatment
A pregnancy test result itself does not require treatment. If the test is positive, next steps involve confirming the pregnancy and beginning prenatal care. If the test is negative but you are trying to conceive, you may get advice on timing intercourse or lifestyle changes.
Self-care at home
If positive: start taking a daily folic acid supplement (as advised by your healthcare provider)
Avoid alcohol, smoking, and certain medications; consult your doctor or pharmacist
If negative: try to wait a few days and test again, or see a doctor if periods remain absent
Keep a record of your menstrual cycle to help track your fertile window
Medical treatments
If you have a positive test, your healthcare provider will recommend routine pregnancy care, which may include blood tests, urine checks, and ultrasounds. No specific medications are given just because of a positive test. If you have difficulty getting pregnant, your doctor may suggest fertility evaluation or treatments, but these are beyond the scope of a home pregnancy test.
When is surgery considered?
Surgery is not needed for a pregnancy test. However, if a pregnancy is found to be ectopic (outside the uterus) or there are complications, surgery may be required. This is a medical emergency and would be handled by a hospital team.
Living with this condition
A positive pregnancy test marks the beginning of pregnancy. You will need to schedule regular care with a midwife or doctor to monitor your health and your baby’s growth. A negative test, if you are hoping to conceive, can be a time to review your cycle and talk to a healthcare professional.
Lifestyle tips
If pregnant: eat a balanced diet, stay active (with your doctor’s advice), and avoid harmful substances
If trying to conceive: maintain a healthy weight, manage stress, and have sex around your fertile window
If not planning pregnancy: consider reliable contraception and discuss options with your healthcare provider
Diet and exercise
If you are pregnant, eat foods rich in folic acid, iron, and calcium. Gentle exercise like walking or swimming is safe with your doctor’s okay. If not pregnant, a healthy diet and regular exercise support overall fertility.
Mental health and emotional wellbeing
The result of a pregnancy test can bring strong emotions – joy, anxiety, disappointment, or surprise. It is normal to feel a range of feelings. If you find it hard to cope, talk to your healthcare provider or a counselor. You are not alone.
Prevention
A pregnancy test is a diagnostic tool, not something to 'prevent'. However, false results can be prevented by following the instructions carefully, testing after a missed period, and using the test before its expiry date.
Screening programmes
Pregnancy tests are a form of screening for pregnancy. Routine prenatal screening (such as blood tests and ultrasounds) is offered after a positive test to monitor the health of the pregnancy.
Complications
If left untreated
A false negative could lead to a delay in starting prenatal care if you are actually pregnant
A false positive could cause unnecessary worry, though this is very rare
Ectopic pregnancy (if a positive test is accompanied by pain or bleeding) is a serious complication that can be life-threatening if not treated immediately
Long-term outlook
When used correctly, pregnancy tests are highly reliable. A positive result opens the door to early prenatal care, which improves outcomes for both the pregnant person and the baby. A negative result can provide clarity and help you plan next steps. In either case, your healthcare team is ready to support you.
