Q1: How Soon Can a Blood Test Detect Pregnancy?
There are two types of blood tests: quantitative and qualitative. The former measures the exact amount of hCG in the body, while the latter provides a yes or no answer to your pregnancy. These tests can be performed, with accuracy, 7 – 12 days after conception has occurred.
Urine tests are not accurate until 14 days after conception.
Blood tests allow for results nearly a week earlier than their counterparts, but there is a wait time to find out the results, which will be discussed in detail shortly.
Q2: Can A Blood Pregnancy Test Be Wrong?
Yes. All pregnancy tests have a slight error of margin. A negative blood pregnancy test has a higher level of error than a positive test. The main issue is that a lot of soon-to-be mothers choose the qualitative test.
With this test, the results may be given sooner, but they’re slightly less accurate.
The qualitative tests will show a positive pregnancy when a reading is just 25 hCG in the body. While this amount does indicate pregnancy, the quantitative test would show the exact amount. A woman with a reading of 100 hCG is, with near certainty, pregnant. However, a woman that has a reading of 25 hCG could be having other issues causing her hCG levels to spike.
Q3: How Long Does A Blood Pregnancy Test Take?
No exact duration can be given for the time it will take to receive the laboratory results on your pregnancy test. Each laboratory is different, and the precise timetable will be explained by your doctor.
Under normal circumstances, tests will be returned to the doctor in 2 – 3 days.
A small amount of clinics may have an on-site lab that will conduct blood tests in-house. In this case, the results may be provided within hours of taking the test.
Q4: How Accurate Are Blood Pregnancy Tests?
Pregnancy blood test results have an accuracy rating of 99%. These tests can accurately measure hCG when the levels would be otherwise undetectable using urine or other methods of testing.
This accuracy level increases later into the pregnancy. Even a couple days will provide results that are more accurate.
In comparison, the standard urine test that you’ll find in many pharmacies have an accuracy level of 97% on average. There is always a chance that your test will come back with an erroneous result, but the chances are 1 in 100 for blood tests.
Pregnancy blood test levels of hCG need to be much lower to determine pregnancy, which is why they’re the preferred method of pregnancy detection.
Q5: Where Can I Get A Blood Pregnancy Test?
A blood pregnancy test can only be sought at a medical facility. Your OBGYN or medical doctor will be able to provide you with a test. Nearby clinics for pregnant women will also offer a low-cost method for pregnancy tests.
Q6: How Much Does a Blood Pregnancy Test Cost?
A major consideration is the cost of a blood pregnancy test. Unless you’re able to get a free blood pregnancy test, offered at few clinics, you’ll either need to have an insurance provider cover the cost, or pay the bill out-of-pocket.
Ask your insurance provider if a pregnancy test will be included under your policy.
In the event that your provider will not cover the costs, it’s important to note that many tests will also check for various diseases and illnesses. This will raise the price of the test dramatically. A test that does include all of these extras can cost $900 or more in some circumstances.
Note: The doctor and lab costs will be returned in separate bills, so expect a bill from each provider following your test.
A standard pregnancy blood test will cost $50 – $200 with the doctor’s bill not included. Planned Parenthood offers a sliding scale rate so that women pay only what they can afford for pregnancy tests. This is a figure derived from your current income level. Many of these facilities have been closed down or are now underfunded, so they may or may not exist in your area.
Q7: Are There At-home Blood Pregnancy Tests?
Blood tests must be conducted at a medical facility. The main issue is that blood needs to be handled properly and sent to a professional lab where the testing procedure can take place. Urine pregnancy tests are nearly as accurate, 97% accuracy, and can be performed at-home.
Q8: Why Are Pregnancy Tests Inaccurate?
When a test is wrong, there are a variety of factors that need to be considered. First and foremost, the test may have been handled inappropriately, degrading the blood sample. There is also a possibility that an error occurred due to the fault of the laboratory where the testing procedure took place.
Some women will not produce hCG as fast as others, so even a slight delay in the production of this hormone can cause qualitative tests to be wrong.
Certain diseases or sicknesses can cause hCG to be present in the body even if pregnancy has not occurred. Cancer has been known to produce a positive pregnancy test that was inaccurate due to the presence of cancer in the body.
If you’re not experiencing other pregnancy symptoms and signs shortly after the test results come back, it’s important to keep a clear line of communication open with your doctor. Thorough testing can be performed to ensure that pregnancy has occurred and that you and the baby are both healthy.
A woman’s body, more precisely the placenta, will start producing hCG when pregnancy has occurred. This happens so that the body dos not reject the fetus because it’s a foreign body. These levels will double in a short amount of time and continue to do so until they have reached a very high level.
Pregnancy tests will test for the level of hCG in the body.
Urine tests and the qualitative blood test will trigger a positive result when hCG levels are above 25. In this case, there are very few errors in testing as there are few circumstances when hCG is produced by the body.
Quantitative tests are a little more data dense and provide the exact level of hCG in the body. Even small amounts can indicate that pregnancy has taken place. In essence, the quantitative test can demonstrate, with a higher level of certainty, that a woman is pregnant due to the precise data points present.
Q10: Should I Opt for a Blood Pregnancy Test?
Under normal circumstances, women will use an at-home test due to the lower pricing and the level of privacy experienced. If an at-home test is positive, it’s important to consult with your medical doctor to have further testing conducted.
An in-doctor visit is the best way to ensure that pregnancy has occurred.
In the event that a test is negative, retake the test within one week. This allows enough time to pass for hCG levels to reach detectable amounts. If the test was negative twice, there is a good chance that pregnancy has not occurred.
