Walgreens Early Result Pregnancy Test Sensitivity
Walgreens has a long history and operates thousands of stores that make it a convenient place to shop. Along with selling national brands of health and beauty products, Walgreens sells its own line of Walgreens-branded products.
As you might guess, Walgreens doesn’t make the products that carry its logo. Instead, the firm buys products from contract manufacturers, re-labelers, and specification developers. These companies specialize in producing store-brand and generic products.
Walgreens only chooses the best contract manufacturers and distributors to carry its respected Walgreens label. For this reason, the company offers a 100% satisfaction guarantee for all its goods.
Walgreens Early Result Pregnancy Test Sensitivity
You came here, to CPG Health, because you want to know details about a particular Walgreens product: The Walgreens Early Result Pregnancy Test.
First, let’s talk about what you mean by the term, “sensitivity.”
What is Pregnancy Test Sensitivity?
Pregnancy test sticks contain a strip of chemically treated paper. The paper reacts to the pregnancy hormone known as human chorionic gonadotropin (HCG).
After conception, the amount of HCG in your system increases, often doubling every few days. After a while, the amount of HCG in your system exceeds typical, non-pregnant levels, triggering a pregnancy test positive result.
High HCG Sensitivity
A pregnancy test with high sensitivity detects a lower amount of HCG. For this reason, they can confirm pregnancy sooner than a standard or low sensitivity pregnancy test.
Before you get excited about a high sensitivity pregnancy test, you need to know that they have a downside. Particularly, a high sensitivity test may give you a false positive.
You see, not every woman’s body works the same. They all have a certain amount of HCG, even when not pregnant. Also, some women have higher “normal” levels of HCG than others.
So, if you have a little more HCG than “typical,” you could get a positive pregnancy test result without being pregnant.
You also need to know about two different measures of pregnancy test sensitivity: Cut Off and Analytical/Clinical.
HCG Cut Off Sensitivity
HCG Cut Off sensitivitiy is the level of HCG that must be present in a urine sample for at least half of users to trigger a positive result. Typically, Cut Off sensitivity is lower than Analytical sensitivity.
If you have the Cut Off concentration of HCG in your system, you have a 50% chance of getting a positive pregnancy test result. You also have a 50% chance of getting a pregnancy test negative.
HCG Analytical/Clinical sensitivity
The Analytical Sensitivity of a pregnancy test is the concentration of HCG that triggers a positive result for every user. In other words, 100% of women who have the Analytical concentration of HCG in their urine will have a positive pregnancy test result.
IMPORTANT: When you talk about pregnancy test sensitivity you must know the difference between “Cut Off” and “Analytical” sensitivity ratings. ALSO, you must know whether the sensitivity value supplied to you by your pregnancy test vendor is Cut Off or Analytical.
What is an early result pregnancy test?
An early result pregnancy test has a high HCG sensitivity. Therefore, it can detect elevated HCG sooner than a standard low sensitivity OTC pregnancy test. It can, therefore, tell you if you’re pregnant before the day of your missed period.
In fact, many early result pregnancy tests allow you to test five or six days sooner. This is good as long as you realize that you may have a false positive.
IMPORTANT: Whenever you use an early result pregnancy test, test again in several days using a fresh test unit. This will help you confirm a positive pregnancy test result.
Walgreens Early Result Pregnancy Test Sensitivity
If you carefully examine the packaging of your Walgreens Early Result Pregnancy Test, you will see no mention of sensitivity.
Instead, you’ll see a description of the product’s accuracy.
Sensitivity vs. Accuracy
As already noted, “sensitivity” refers to the concentration of HCG required to trigger a 50-50 positive result or a 100% positive result. This value affects accuracy, but it’s a different parameter.
Accuracy refers to the likelihood that you’ll have an accurate result.
Most OTC home pregnancy tests tell you that they are over 99% accurate from the day of your expected/missed period.
If you test early, you almost always sacrifice the accuracy of your result. In other words, as you test before your expected period, you can expect a higher incidence of incorrect results.
So, when you think about sensitivity, remember that a high sensitivity test results in low accuracy when you test before the day of your EMP.
Early result and standard pregnancy tests are over 99% accurate from the day of your expected period.
The following chart tells you how testing early affects the accuracy of your pregnancy test result:
False negatives vs False positives
Standard pregnancy tests have a low HCG sensitivity, so testing early usually results in a false negative.
Early result pregnancy tests have a high HCG sensitivity, so testing early often results in a false positive.

Here’s the information you’re looking for about Walgreens Early Pregnancy Test sensitivity:
Walgreens Early result HCG Analytical Sensitivity
The results demonstrated that the analytical sensitivity of the new device (thelowest concentration that yields 100 % of positive results) is 10 mIU/ml.
In other words, 100% of women with an HCG concentration in their urine of 10 mIU/mL will receive a postive pregnancy test result while using the Walgreens Early Result Pregnancy Test.
Walgreens Early result HCG Cut Off Sensitivity
The Cut Off sensitivity of the Walgreens Early Result Pregnancy Test is approximately 8.5 mIU/mL. In fact, laboratory test results indicated that 57% of women with an HCG concentration of 8.5 mIU/mL received a positive pregnancy test result. 43% received a negative.
Only 17.7% of women with an HCG concentration of 7.5 mIU/mL received a positive pregnancy test result.
To develop a further understanding of sensitivity measurements for the Walgreens Early Result Pregnancy Test, please review the following chart:
Using this chart, you can visually verify what we’ve previously reported:
- HCG Cut Off Sensitivity: 8.5 mIU/mL.
- HCG Analytical Sensitivity: 10 mIU/mL.
Walgreens Early Result Pregnancy Test vs. First Response Early Result Pregnancy Test
FRER, the gold standard for pregnancy test sensitivity has a lower HCG Cut Off sensitivity (6 mIU/ml) vs. Walgreens (8.5 mIU/mL).
Interpreting HCG Cut Off sensitivity
You have a 50% chance of getting a positive result with FRER at 6 mIU/mL, so you can potentially get an earlier positive result. Keep in mind, however, that the accuracy of your result is only 50%.
Meanwhile, with the same 6 mIU/mL HCG concentration, you will have a zero-percent chance of receiving a positive result with the Walgreens Early Result Pregnancy Test.
You have a lower chance of receiving a false positive pregnancy test result when you choose the Walgreens Early Result Pregnancy Test.
Interpreting HCG Analytical sensitivity
When comparing Walgreens Early Result Pregnancy Test with FRER regarding HCG ANALYTICAL SENSITIVITY, they both have identical values (10 mIU/mL).
Both the Walgreens and First Response Early Result Pregnancy Tests have the same accuracy for women that have n HCG concentration of 10 mIU/mL.
Does 10 mIU/mL mean I’m pregnant?
By most standards, 10 mIU/mL is considered as an “elevated” HCG level. Many women who test positive at 10 mIU/mL will test negative with a standard pregnancy test on the day of their missed period.
When using an Early Result Pregnancy Test, always test again later to verify your result.
