What to Look for in a Pregnancy Test
Finding out you're pregnant can be an exciting yet nerve-wracking time. Using an accurate and easy-to-use pregnancy test helps provide reliable results quickly so you can take the next steps in your prenatal care. When evaluating at-home pregnancy tests, here are some key features to consider:
Sensitivity Rating
Sensitivity indicates the minimum hCG hormone threshold needed to trigger a positive result. Tests with a rating of 10 mIU/ml or lower detect pregnancy sooner. Early Result tests can get positives around 5 days before a missed period.
Accuracy
Accuracy reflects the test's ability to correctly diagnose pregnancy with few false positives or negatives. Highly accurate tests use more advanced technology to reliably determine hCG levels and reduce errors.
Readability
Look for clear, easy-to-interpret result screens. Digital or spell-out readings reduce confusion over faint lines. Smartphone app connectivity offers additional result confirmation and tracking tools as well.
Premom Ovulation and Pregnancy Test Reviews
Premom combines ovulation and pregnancy testing into complete at-home fertility tracking solutions. But do their products deliver reliable results? Here is an overview of Premoms’s accuracy and usability for trying to conceive and confirm pregnancy.
Early Detection Pregnancy Tests
Premom’s early detection pregnancy strips can find hCG levels as low as 10 mIU/ml for 6 days sooner testing ability. The test cassette features an easy-to-read digital display. Users also photograph results for interpretation and tracking via the Premome phone app.
Pros
Premom’s pregnancy tests offer excellent sensitivity for prompt detection after conception. The app creates an organized system for tracking fertility and saves photographic records of each test. At 20 affordable test strips per pack, frequent testing is budget-friendly.
Cons
Although the app reads results accurately most times, it occasionally glitches or will not upload properly. Thankfully, the test itself gives a very clear pass/fail indicator without needing the app. As an early detector, Premome is not recommended for full pregnancy dating.
Accuracy
Overall, Premome pregnancy tests provide accurate, early detection on par with top competitors. False positives or negatives issues mainly arise from user errors like improper testing rather than test failures. Estimated accuracy rate: 99%

How to Take a Pregnancy Test for Best Accuracy
Read All Instructions Carefully
Following the test guidelines properly is vital, from knowing when or how to take the test to interpreting results accurately. Different test brands have different testing windows or methods.
Use First Morning Urine
HCG levels build up overnight as you sleep, making first morning urine the most concentrated sample all day. This helps pregnancy tests better detect the hormone for accurate readings.
Retest if Needed
If taking the test too early or improper usage causes an unclear result, retest 1-2 days later. Home pregnancy tests are around 99% accurate the day of a missed period onward when directions are followed.
Pregnancy Test Result Interpretation
Once the testing timeframe passes, check how to translate your test results - whether from traditional lines, digital readout, or app. Photos help compare any faint lines to diagrams showing positive vs negative tests.
Digital/Spelled Out Results
"Pregnant" or "Not Pregnant" displays eliminate confusion over line results. Some also indicate conception timeframes like 2-3 weeks to aid dating. A few give error notifications if defective.
Lines Explained
Lines indicate pregnancy test reactivity:
- No line = invalid, retest
- One line (control line only) = not pregnant
- Two lines (control + test line) = pregnant
App Tools
Apps provide additional analysis like lines overlays, tracking features, appointment reminders and can upload tests for remote doctor review. Some connect tests to Bluetooth for automation.
Types of Pregnancy Tests
Strip Style
Pregnancy test strips, sticks or dipsticks are the most common style. Absorbent testing tips collect urine samples. Lines appear denoting test reactivity and pregnancy status.
Midstream Tests
Midstream tests, also known as cassette tests feature an angular design allowing urine collection during a midstream sample. Helpful for sanitary handling.
Digital Tests
Digital pregnancy tests provide easy “pregnant” or “not pregnant” text-based readouts, great for clear, unambiguous results. Advanced models add conception indicators and app connectivity.
Early Detection/Sensitive Tests
Early detection pregnancy tests can get positives around 5-7 days after conception/before a missed period thanks to low sensitivity levels around 10-20 mIU/hCG. They use special indicators.
How Do Pregnancy Tests Work?
Home pregnancy tests detect the presence of human chorionic gonadotropin (hCG), a hormone released by a developing placenta starting around 5-7 days after fertilization. Here’s what happens behind the scenes:
Absorbent Tip
The test strip wick soaks up urine as it flows past labels antithetical to an antibody on the test strip. The antibodies only bind to hCG.
Antibody Reaction
If hCG is present, the antibodies grab hold of hormone molecules and migrate across the test strip carrying conjugated dye. More hCG generates more dye migration.
Control Lines
The control line verifies proper antibody reaction and strip function. Comparative dye intensity between control and test lines indicates pregnancy status.
Digital Interpretation
Digital pregnancy tests contain special sensors measuring dye deposit amounts. Greater dye deposits generate “pregnant” readings based on pre-set hCG thresholds.
What Causes False Positive or False Negative Results?
False Negative Causes
False negative results wrongly indicate non-pregnancy. Common reasons include:
- Taking the test too early before sufficient hCG builds up
- Improper test use like not following all directions
- Testing with overly diluted urine
False Positive Causes
False positives incorrectly signal pregnancy, often due to:
- Chemical pregnancies or early miscarriage
- Menopause or medical conditions producing hCG
- Issues like expired test components or antibodies detecting similar hormones
Retesting helps confirm unclear early or borderline test results. If you repeatedly get positives then negatives, see your doctor to investigate potential pregnancy related concerns.
Interpreting Pregnancy Test Faint Lines
Faint lines cause the most confusion in interpreting pregnancy test stick results. Here’s when faint test bands indicate pregnancy or not:
Any Visible Test Band = Positive
Even the faintest visible vertical line in the results area means the test detected hCG and signals pregnancy. If no line appears, then the test is negative.
Darker Test = More hCG
Line color intensity correlates with higher hCG levels present to trigger more significant dye deposits. A darker test line means greater pregnancy progression.
No Line Visible In 10 Minutes = Negative
Test strips record results within a set time, like 3-5 minutes for early detection and 3-10 minutes for other tests. Any lines appearing after the testing timeframe may be moisturization errors so retest to confirm.
Pregnancy Test FAQs
How Soon Can I Take a Pregnancy Test?
Today’s early detection pregnancy tests can find hCG around 5-7 days past conception. Waiting 7-10 days post ovulation yields over 99% accurate results as enough hormone builds up to trigger reliable positive readings.
Which Brand of Pregnancy Test is Best?
Clearblue, First Response, and easy@home consistently rate well for early, sensitive detection with easy to interpret results. Premome tests also live up to their promises of early hCG finding and app tools.
When Should I Take a Pregnancy Test After IUI or IVF?
Quantitative hCG blood tests ordered by your doctor offer the earliest insight into success rates around 7-10 days post embryo transfer. At-home urine tests generally detect pregnancy around the 2 week wait mark, sometimes a few days sooner.
FAQs
Can I retake a pregnancy test if I get an unclear result?
Yes, you can retake a pregnancy test if the first response is faint, ambiguous, or otherwise questionable. Use first morning urine and follow all test directions precisely. If still unclear after a day or two retest, see your doctor.
What do error symbols on a digital test mean?
Digital pregnancy tests may display error symbols or invalid notifications if the test malfunctions due to things like outdated components or improper usage. Disregard the results and retest with a new kit.
How much do pregnancy tests cost?
Pregnancy test costs range widely from $0.50-$2 for test strips to $10-$15 for midstream kits or combo packs. More advanced digital or bluetooth enabled tests run $15-$35. Shop sales for better deals.
Can tests with blue dye give false positives?
While tests using blue dye instead of pink can reliably detect pregnancy, some brands tend to run slightly higher chances of evaporation lines wrongly indicating positive results if read outside the time limit.
