Positive Lines: All About Pregnancy Test

For married couples, a pregnancy test is one of the most amazing, make-or-break things that they are going to take when they decide to start a family. In most cases, it comes in the form of a simple plastic stick, but its results can either be glorious or devastating to an expecting couple.

When the terms “pregnancy test” come to mind, people usually think about two lines and a hearty, happy dance. Actually, this kind of test is only one of the two types of determining pregnancy. What is the other one? Read all about it— and more— in this simple, road-to-pregnancy guide.

Type of Pregnancy Test

If you are experiencing any symptoms of possible pregnancy (missed menstruation, nausea, increased food craving, etc.), you can confirm it by taking any of the following (or both, just to be sure):

Urine Test

This is the most common— and inexpensive— type of testing pregnancy. A urine test can be performed in a clinic or, the more popular option, by using home pregnancy tests (HPT).

Urine pregnancy tests work by identifying the hormone human chorionic gonadotropin (hCG) in a urine sample, which is only present when you are pregnant. It is recommended to take a urine test at least twice, because some women’s hCG levels vary in terms of detection.

Home Pregnancy Test

Home pregnancy tests can be purchased in drugstores (over the counter), and usually look like a simple stick, with a result window that is either digital or analog. It can be dipped in the collected urine or held straight in the urine stream. After quite some time (most brands suggest a 10-minute waiting time for accurate results), two lines will emerge in the result window, indicating that you are, indeed, pregnant. Sometimes, the result can be a plus symbol or the actual word “pregnant.”

Urine tests— clinical or HPT— give the same result, even if they are done in different locations. They both rely on urine and hCG levels, so it does not matter which one you will use. The only advantage of testing in a clinic, however, is that you can easily ask a doctor about the procedure and results.

Blood Test

Some women are not comfortable with home pregnancy tests; this is why they opt for a blood test to double-check and make sure that the results are accurate.

When it comes to blood pregnancy tests, doctors usually check the blood in two ways:

  • Quantitative blood test – Also called the beta hCG test, this type detects and measures the exact number of hCG in the blood— even the tiniest hCG there is— which makes it very accurate.
  • Qualitative blood test – Unlike the quantitative test, this one only determines if the hCG is present in the blood or not, making it deliver a “yes” or “no” answer only.

These blood pregnancy tests are exclusively taken at clinics or doctor’s office. It is also more expensive compared to home pregnancy tests, but it can detect amounts of hCG much earlier than the latter. So, if you have enough money to spare, it is recommended to give blood test a try.

How Accurate Are Pregnancy Test?

When taking a pregnancy test, accuracy is very, very important. Women simply cannot (and should not) bear false positives or false negatives when it comes to finding out the real status of their pregnancy.

So, just how accurate are pregnancy tests?

Urine test

Even though urine tests— especially home pregnancy tests— cost less than blood tests, they can be as accurate as the latter. If done properly and on the right time, an HPT can deliver 100% correct results— even if taken only once.

However, it is the responsibility of the user to assure the right way of using a home pregnancy test. All HPT kits include instruction manuals, so make sure to read all pointers carefully before proceeding with the test. If it says “wait 10 minutes after doing the test,” willingly comply because it can affect the result of the test.

Blood Test

A quantitative blood test, because of its ability to exactly count the number of hCG in the blood, can be the most accurate pregnancy test of them all. Since it can detect even the tiny hCGs, there is no doubt that the result of a quantitative blood test is reliable and precise.

Meanwhile, a qualitative blood test shares the same level of accuracy as a urine blood test. Since it can only detect the presence of hCG, its reliability is not the same as a quantitative blood test.

Where To Purchase Pregnancy Tests?

So, have you decided which pregnancy test to take? If the answer is yes, then it is time to find out where you can acquire your choice of test.

Blood/Urine test

Blood pregnancy tests and clinic urine tests can only be performed in a health facility, such as hospitals, clinics, or doctor’s office. They make use of highly-specialized equipment to accurately determine if you are pregnant or not, and, unlike home pregnancy tests, doctors can be within your reach if ever you have questions or concerns.

Home pregnancy test

Home pregnancy tests vary, depending on the brand and type (digital or not), with prices ranging from $1 to a little over $40.

This kind of pregnancy test is easily available in all drugstores in the United States, and it can be readily purchased over the counter, without so much fuss and no questions asked. For example, Walgreens offer a variety of good home pregnancy test brands, such as Clear Blue (less than $30), First Response (less than $25), and Answer (less than $10). They also have their very own Walgreens Pregnancy Test, which costs $11.99.

Some online stores also offer pregnancy test kits, although you should be careful when making a purchase on the Internet. Make sure that the website is legitimate, like AccuratePregnancyTests.com, which offers HPTs for less than $5.

Where To Purchase Pregnancy Tests?

Pregnancy tests yield different results, depending on the person taking it. While to some women, all it takes is one try, most women have to double-check— even triple-check— just to verify the accuracy of the test.

The bottom-line is it all boils down to the person taking the test. With responsible and proper use of pregnancy tests, you can be sure that the result will be reliable and trustworthy.

Blood Pregnancy Test

You are now several days post ovulation and you suspect that this might be the cycle that you conceived! The next question that you might ask yourself is: should I run to the doctor for a blood pregnancy test or should I take a home pregnancy test?

Like most questions related to fertility and pregnancy, there is no straightforward answer to this question. Both a blood pregnancy test and a home pregnancy test will identify the presence of the pregnancy hormone called human chorionic gonadotropin (hCG), and will determine if you are pregnant or not. So, to determine which test is right for you, you might want to consider convenience, expense, accuracy, and your fertility history.

There are actually two different types of blood pregnancy tests, also called pregnancy serum tests. One type, called a quantitative blood pregnancy test (or a beta hCG test), measures the exact amount of hCG in the blood, while a qualitative blood pregnancy test simply provides confirmation of the presence of hCG, and a “yes” or “no” answer for pregnancy. If the blood pregnancy test reveals that hCG is under 5 mIU/ml, then the test will be considered negative. If the level of hCG is determined to be between 5 and 25 mIU/ml, this is said to be an equivocal result, and another test should be performed in a few days to confirm pregnancy.

As for home pregnancy tests, there are several types to choose from. All home pregnancy tests (HPT) detect the presence of hCG in urine, and come either in a test strip, midstream or digital format. With the test strip or midstream format, you will dip the strip in a urine sample or urinate directly on the stick, wait a few minutes, and watch for the appearance of a colored test line to appear, which indicates a positive result. A digital test will typically provide a definitive “no” or “yes” in words that appear on the digital display. Each unique HPT is calibrated to detect a specific level of hCG in the urine, such as 20 mIU/ml, 50 mIU/ml or 100 mIU/ml. More “sensitive” tests, those that are able to detect a lower amount of hCG, can provide an accurate result as early as 7-10 days post ovulation.

When deciding if you should use an HPT or have a blood pregnancy test done at the lab, here are a few items to consider:

  • Convenience: While it is true that a quantitative blood test can confirm pregnancy a couple of days before an early detection HPT, a qualitative blood test that is set to detect 25 mIU/ml is no more sensitive than an early detection HPT. Many women find it more convenient to simply wait a day or two and take a pregnancy test in the privacy of their home. In addition, an HPT will typically produce results in just minutes. On the other hand, you might be on pins and needles for up to 48 hours while you wait for results from a blood pregnancy test.
  • Expense: The out of pocket expense for a blood pregnancy test will vary depending on the clinic you choose and the type of insurance you have. You should expect to pay up to about $75 for this service. And, if the results are uncertain (hCG level between 5 mIU/ml and 25 mIU/ml), a retest will be required in a few days, which will in most cases incur an additional fee. On the other hand, you can purchase 10 early detection pregnancy test strips for about $10, which will allow you to test several days in a row if necessary.
  • Accuracy: The most “accurate” pregnancy test is the quantitative blood pregnancy test, as it determines the exact amount of hCG in your blood. This will allow your doctor to make a very clear determination about whether or not you are pregnant or if a retest is required in a few more days. With both a qualitative blood test and an HPT it is possible to get a false negative result. This means that if the test is not sensitive enough to detect your current level of hCG (for example, your current level is 20 mIU and the test is set to detect hCG at 25 mIU), you will get a negative test result even though you are pregnant. If you get a negative result from an HPT or a qualitative blood test, and you continue to have any signs of pregnancy, we recommend retesting in a few days.
  • Fertility history: If you have experienced a miscarriage or an ectopic pregnancy in the past, your doctor may well want to monitor your hCG levels closely in the first several weeks of pregnancy. In the early days of pregnancy, hCG levels double every 48-72 hours. (See the chart below for average blood hCG levels as pregnancy advances). If hCG levels do not rise appropriately in those very early days, it can signal a problem with the pregnancy. By monitoring your exact hCG levels with regular quantitative blood test, your doctor may be able to detect a problem early on. Neither a qualitative blood test nor an HPT allows this type of monitoring, as they do not reveal exact amounts of hCG, and cannot determine if levels are increasing appropriately.

The following is a list of blood hCG levels achieved as pregnancy advances (LMP means last menstrual period):

  • 3 weeks since LMP: 5 – 50 mIU/ml
  • 4 weeks since LMP: 5 – 426 mIU/ml
  • 5 weeks since LMP: 18 – 7,340 mIU/ml
  • 6 weeks since LMP: 1,080 – 56,500 mIU/ml
  • 7 – 8 weeks since LMP: 7,650 – 229,000 mIU/ml
  • 9 – 12 weeks since LMP: 25,700 – 288,000 mIU/ml
  • 13 – 16 weeks since LMP: 13,300 – 254,000 mIU/ml
  • 17 – 24 weeks since LMP: 4,060 – 165,400 mIU/ml
  • 25 – 40 weeks since LMP: 3,640 – 117,000 mIU/ml
