Bottom Line

The First Response Early Result Pregnancy Test is the one to use if you can't wait until your period's supposed to start to find out if you're pregnant: It's 58 percent accurate a full four days before a missed period. Even if you're not in a hurry, this is still one of the most accurate tests on the market.

Accuracy

Highly accurate when used as directed. The First Response Early Result Pregnancy Test claims to be 68 percent accurate six days before a missed period, but scientific evidence disputes that. An independent test measuring the accuracy of claims of six home pregnancy tests shows the First Response Early Result to be only 25 percent accurate at six days before an expected period. That rises to 58 percent accuracy at four days before and 100 percent accuracy the day after a missed period.

Users rank this test highly for accuracy, with many saying it gave them accurate positive results even earlier than six days before their expected period start date. Like all pregnancy tests, First Response Early Result assumes an approximate 28-day cycle. Women with longer cycles may take longer to build up enough human chorionic gonadotropin (hCG) for positive testing, which can lead to a fairly high rate of false negatives. Because this test can be used so early, it will detect hCG from a very early miscarriage, meaning the test is correct but the pregnancy wasn't viable.

The test's control line is said to be consistent and unmistakable, but there are occasional complaints of a completely blank results window.

Sensitivity

Most accurate test available. First Response says the Early Result Pregnancy Test can detect hCG levels of as low as 25 mIU/ml. However, independent studies show it can detect levels as low as 2.1 mIU/ml in a small percentage of cases, and many women report getting a positive at 5.5 mlU/ml.

Ease Of Use

Early positives may be faint. The instructions on the First Response Early Result Pregnancy Test are easy to read and understand, users say. You can urinate directly on the absorbent tip, or collect urine and dip the absorbent tip for five seconds. Doing so first thing in the morning is recommended, especially in early cycle testing. The test should be read at thee minutes and immediately discarded. A single pink line means negative, a second pink line means positive. There's no evaporation line, but any results that appear after the three-minute mark aren't considered reliable because the positive results line can take on a faint color after 10 minutes.

Users' primary confusion with First Response Early Result comes in the form of a faint positive line when testing very early in pregnancy, leading some to question whether they see it. Experts say even a very faint line is a positive if it's read at the proper time. Since the rate of accuracy is estimated at close to 100 percent the first day of a missed period, urine should be retested then.

1. Clinical Chemistry

Review Credibility: Very Good This clinical study evaluates the urine samples of 120 known pregnant women to confirm the claims of early pregnancy detection of six tests. First Response Early Result is the most sensitive, able to detect 2.1 mIU/mL of regular hCG 25 percent of the time at six days before an expected period. It's 96 percent accurate on the day of an expected period, detecting 70 mIU/mL. Perfect 100 percent accuracy is achieved on the first day after a missed period, when hCG levels were 143 mIU/mL.

Review Credibility: Very Good With about 5,800 pregnancy test results here, the First Response Early Result earns an overall rating of 4.5 stars out of 5 after more than 80 reviews. Users say it's a very accurate test that can detect pregnancy quite early in the cycle. There are few negative posts. An interpretation of the submitted statistics indicates that the test is most accurate at 10 days past ovulation (DPO), which is four to six days before a missed period for most women. Before that, you're most likely to get a false negative if you're pregnant, but there's still a 26.1 percent chance of a false negative even at 10 DPO.

3. Drugstore.com

Review Credibility: Very Good In more than 115 customer reviews, the First Response Early Result gets 3 stars out of 5. Critics report that nothing showed up when they weren't pregnant, although it's not clear if they mean the control line as well; if that's the case, it's a defective test. Other users say it didn't work six days before their missed periods, but rather eight to 10 days before. The positives far outweigh the negatives, with most women saying they got a faint positive six days before a missed period. Many add that the positive showed immediately without having to wait the three minutes.

6. About.com

Review Credibility: Good About.com's guide to pregnancy and childbirth says the First Response Early Result Pregnancy Test is a quality product that can be used three days before a missed period. First Response advertises that it can be used six days before an expected period, indicating that this may be an older review. Weiss adds that its design seems flimsy, but the test is otherwise accurate and easy to use. It gave a positive result in 70 seconds on a woman who was five weeks pregnant.
