About the test

Progesterone is an important female sex hormone and one of its key roles is to prepare the lining of the womb to receive a fertilised egg.

Levels of progesterone rise and fall throughout the menstrual cycle. In a standard 28 day cycle, ovulation occurs on day 14 (where day 1 is the first day of your period). Following this, levels of progesterone rise, reaching a peak at day 21 (a level above 30nmol/L indicates that ovulation has occurred).

If your cycle is a different length, then you should take the test 7 days before you expect your next period to begin e.g. if you have a 35 day cycle you should take the test on day 28.

Most of the biomarkers we offer in the "ready made" panels are also available separately. So if your favourite test panel is missing a biomarker you would like to have, no problem, you can add whatever you need to one of our standard panels using the "Pick-n-mix" options, such as this one.


    For most biomarkers our usual turnaround time is 24-48 hours, or less, from the time your sample is in our lab. We do not wait for all the results to complete before sending them to you, so you may start receiving results the same day for most cases, or as results become available.

    We are extremely proud of our very short turnaround times and a very efficient laboratory processes. Whilst we accommodate the shortest of time scales, with some results available within hours, for this particular test the usual turnaround time is:

    1-2 days

Doctor's notes

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

Irregular menstrual cycles, such as unusually long cycles or missed periods, may warrant investigation into hormone levels including progesterone. A progesterone test can help determine whether ovulation is occurring and if there are any hormonal imbalances contributing to menstrual irregularities.

Red flag symptoms for the Progesterone Blood Test

Even if your blood tests are normal, you should see a doctor if you have any of the symptoms below because they may be a sign of serious underlying illness. 

  • Unexplained weight loss.
  • Drenching sweats during the night.
  • Persistent fevers.
  • Progressively severe symptoms of any kind.

Special instructions

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Progesterone Blood Test.

Progesterone levels can fluctuate throughout the menstrual cycle and during pregnancy, so the timing of when progesterone should be measured depends on the specific reason for the test.

  1. Menstrual cycle monitoring: If the goal is to assess ovulation or evaluate the luteal phase of the menstrual cycle, progesterone is typically measured about 7 days before the expected start of the next menstrual period. This timing corresponds to the peak of progesterone production after ovulation. For example, if your cycle is typically 28 days, then progesterone should be measured around day 21.
  2. Fertility assessment: In the context of fertility evaluation, progesterone is often measured in the mid-luteal phase of the menstrual cycle (around 7 days post-ovulation) to confirm ovulation. This helps determine whether progesterone levels are adequate to support a potential pregnancy.
  3. Monitoring early pregnancy: If there are concerns about the viability of a pregnancy or risk of miscarriage, progesterone levels may be measured in early pregnancy. However, the timing for this measurement can vary depending on the specific circumstances and healthcare provider requirement. We cannot advise on timings in this case, please refer to your requesting practitioner.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • That’s it! We’ll do the rest.

Home test kit for Progesterone Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

Frequently Asked Questions

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

What is the role of progesterone in the body?

Progesterone is a hormone primarily produced by the ovaries following ovulation during the menstrual cycle. Its main role is to prepare the uterus for pregnancy by thickening the lining (endometrium) to support implantation of a fertilised egg. If pregnancy occurs, progesterone helps maintain the uterine lining and prevents contractions that could lead to miscarriage. In addition to its role in pregnancy, progesterone also plays a part in regulating the menstrual cycle, supporting breast tissue development, and influencing mood.

What are the symptoms of low progesterone?

Low progesterone levels can lead to a variety of symptoms, including irregular menstrual cycles, heavy or prolonged periods, infertility or difficulty conceiving, recurrent miscarriages, mood swings, anxiety, depression, insomnia, breast tenderness, and changes in libido. In some cases, low progesterone may also contribute to symptoms associated with premenstrual syndrome (PMS) or perimenopause.

Why take this test?

Hi, I am Dr. Marco Esposito and here is why it's important to take this test.

During early pregnancy, progesterone levels rise to support the pregnancy. A progesterone test is useful to monitor the health of the pregnancy.

Is this test right for you?

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

Low progesterone levels during certain phases of the menstrual cycle can indicate issues with ovulation or potential problems with the ability to sustain a pregnancy.
