When used near the time of a missed period, the First Response Gold Digital Pregnancy Test is highly accurate and results are easy to read. It's not as sensitive to human chorionic gonadotropin (hCG) as manual tests earlier in the menstrual cycle, but users like reading words instead of symbols.
Mixed reviews from users. The First Response Gold Digital Pregnancy Test claims to be 58 percent accurate four days before a missed period, but experts dispute that. An independent study measuring the accuracy of the claims of six home pregnancy tests shows the First Response Gold Digital is only 42 percent accurate at four days before an expected period. That rises to 68 percent accuracy at three days before and 100 percent accuracy three days after a missed period. 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 hCG for positive testing, leading to a fairly high rate of false negatives.
Many users who test very early agree, saying they got either a false negative or false positive. They seem to rate this test lower when they receive an early negative result but don't follow up to confirm whether it was correct. When they get an early positive, some women say they take the test apart to see what the inner strip says, which seems to confuse them further. While digital pregnancy testing is thought to be more accurate, the technological aspect may prompt users to test earlier and disbelieve the results more often, thus affecting accuracy.
Use within a day or so of missed period. The First Response Gold Digital can detect hCG levels as low as 25 mIU/ml, although independent testing indicates it can detect levels as low as 2.1 mIU/ml in 25 percent of tests six days before a missed period. However, it's much more accurate when used closer to the time of the missed period. There's no evaporation line.
Built-in timer. Like all pregnancy tests, the First Response Gold Digital requires the user to either urinate on the stick or dip it in collected urine for five seconds. Results can be read in three minutes. Unlike traditional tests, the Gold Digital has a dual-purpose built-in timer. It not only verifies that the test is working but also counts down to when the test can be read. Users with accurate tests say the results are very clear, with a "yes" for pregnant or "no" for not pregnant.
The First Response Gold Digital activates as soon as it's opened, so it shouldn't be opened until ready to be used.
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 Gold Digital detects 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 in detecting 70 mIU/mL. Perfect 100 percent accuracy is achieved on the third day after a missed period, when hCG levels are 302 mIU/mL.

Review Credibility: Very Good With about 340 pregnancy test results here, the First Response Gold Digital earns an overall rating of 3 stars out of 5 after more than 15 reviews. Reviews are mixed, with reports of both false positives and negatives, but users seem to test very early in the cycle and don't post follow-up comments about later testing. An interpretation of the submitted statistics indicates that the Gold Digital is most accurate at 15 days past ovulation (DPO), about the time a woman would miss a period. Before that, you're most likely to get a false negative if you're pregnant, but there's still a 17.6 percent chance of a false negative even at 15 days DPO.

Review Credibility: Very Good The First Response Gold Digital Pregnancy Test gets 2.7 stars out of 5 after about a dozen reviews. However, several 1-star ratings are based on shipping issues, not the product itself. Most of the other posts give the product 5 stars, with women saying the test is very easy to use, detects pregnancy early in the cycle and provides unmistakable results. A couple of users report getting false positives, but they don't say when they tested.
