Early pregnancy blood test - Too early for a scan? Have a blood test
Introduction
Blood tests play a crucial role in pregnancy, whether it's in preparation with a fertility blood test or in
monitoring the health of the pregnancy throughout. Blood tests are also valuable
in confirming the pregnancy following symptoms of a positive pregnancy test when
the pregnancy is too early to be confirmed by an ultrasound scan. Early pregnancy blood tests play a crucial
role in determining not only whether you're pregnant but also how well the
pregnancy is progressing. While many women confirm their pregnancy with a home
urine test, blood tests provide more precise information and can detect
pregnancy earlier than urine tests. It can be disheartening when a pregnancy
can’t be visualised on the ultrasound scan due to being too early, but a blood
test can provide valuable information and peace of mind that the pregnancy is
progressing healthily.
What Are Early
Pregnancy Blood Tests?
Blood tests in early pregnancy measure levels of specific hormones
produced during pregnancy. The two most important hormones checked through
blood tests are:
1.
Human Chorionic Gonadotropin (hCG)
This is the hormone most commonly associated with pregnancy. It is produced by
cells that form the placenta after the embryo implants in the uterine lining.
The presence of hCG in your blood is a clear sign of pregnancy.
2.
Progesterone
This hormone is essential for maintaining a healthy pregnancy. It helps prepare
the uterine lining for implantation and supports early pregnancy development.
Monitoring progesterone levels can provide insights into the health of the
pregnancy, especially if there are concerns about miscarriage or ectopic
pregnancy.
HCG Blood test: Confirm the pregnancy
A private beta hCG blood test aims to quantify hCG
levels to determine and monitor the pregnancy. Human chorionic gonadotrophin
(hCG) is a hormone which starts to be produced around 6 days after
fertilisation. Many individuals have very low levels of hCG in their blood and
urine when they are not pregnant. HCG tests detect elevated levels which can be
used to determine pregnancy and the progression. Cells that go on to become the
placenta during pregnancy produce the hCG hormone, hCG levels rise quickly
during the first few weeks of pregnancy. HCG levels are not only signal
pregnancy but are also a way to measure whether a pregnancy is developing
correctly.
Monitoring hCG levels Very low HCG levels may point to a problem
with the pregnancy, be a sign of an ectopic
pregnancy, or warn that pregnancy loss could
occur. Rapidly rising HCG levels can signal a molar pregnancy,
a condition that causes a uterine tumour to grow. Often multiple HCG
measurements are required to track the development of a pregnancy. HCG levels
stop rising late in the first trimester. This levelling out may be why many
people experience relief from pregnancy symptoms, such as nausea and fatigue, around
this time.
When Should You Get an Early Pregnancy Blood Test?
Early pregnancy blood tests can be performed as soon as you
suspect you're pregnant. They are typically recommended by healthcare providers
for specific reasons, such as:
·
Early
Detection of Pregnancy: If you’ve
had fertility treatments or are anxious to confirm pregnancy early, a blood
test can provide answers sooner than a home urine test.
·
Uncertain
Results from a Home Pregnancy Test:
If a urine test gives unclear or inconsistent results, a blood test can provide
a more definitive answer.
·
History
of Miscarriage: If you’ve
experienced recurrent miscarriages, your doctor may want to monitor your hCG
and progesterone levels early on to ensure everything is progressing smoothly.
·
Possible
Ectopic Pregnancy: If you
experience unusual pain or bleeding in early pregnancy, a blood test (combined
with an ultrasound) can help diagnose or rule out an ectopic pregnancy.
Slow-rising or abnormal hCG levels could indicate this condition.
Why
Are Early Pregnancy Blood Tests Important?
There
are several reasons why early pregnancy blood tests are important, especially
when it comes to the health and progression of the pregnancy:
·
Confirming Pregnancy- While home pregnancy tests can be quite accurate,
blood tests provide an earlier and more reliable confirmation. If you need to
know early for health or personal reasons, a blood test offers peace of mind.
·
Determining the Age of the Pregnancy - Quantitative hCG levels can give a rough estimate
of how far along you are in the pregnancy, which is helpful if you’re unsure of
your last menstrual period or ovulation date.
·
Monitoring Pregnancy Health - The way hCG levels rise can tell a lot about the
health of your pregnancy. In a normal pregnancy, hCG levels will typically
double every 48 to 72 hours in the first few weeks. If the levels are not
rising as expected, it may be a sign of miscarriage or ectopic pregnancy,
prompting further evaluation by your doctor.
·
Tracking Complications - If you’re at risk for complications, such as
miscarriage or ectopic pregnancy, regular blood tests can monitor hCG levels
over time to detect any early warning signs. A drop in hCG levels in early
pregnancy is often one of the first indications of a potential miscarriage.
·
Evaluating Fertility Treatments - Women undergoing fertility treatments like
in-vitro fertilization (IVF) will have their hCG levels monitored closely after
the embryo transfer. This helps doctors assess whether the treatment has been
successful and if the pregnancy is progressing well.
Early pregnancy
blood tests are an invaluable tool for confirming pregnancy, assessing
gestational age, and monitoring the health of the pregnancy. They provide
essential information that helps doctors diagnose complications early and
ensure that you receive the appropriate care. Whether you're seeking
confirmation of pregnancy or tracking your hormone levels due to concerns,
blood tests offer a reliable and precise way to monitor the start of your
pregnancy journey.
Early detection and
care can make all the difference in a healthy and smooth pregnancy. An early pregnancy
blood test prior to the first scan can provide peace of mind and valuable
information going forward.
