What hormone does the ovulation test detect?

Ovulation tests measure the production of luteinising hormone (LH) in urine. This hormone plays a key role in the female reproductive system. When the production of this hormone increases, it means that ovulation is about to occur one or two days after the test is positive.

Analogue or digital test - what should you pay attention to?

The most important variable in the case of ovulation tests is whether it is analogue or digital. Below, we will explain what the main characteristics of both types of tests are so that you can choose the one you think is best for you.

Analogue test. This type of test works with disposable strips. Once the urine has been placed in a container, you have to immerse the strip to a certain depth and wait for the test line to indicate whether it is positive or not by the intensity of its colour. It is an economical option due to the number of strips included.

Digital test. Digital tests work by depositing urine on a dipstick device. If a smiley face appears after a few minutes, it means ovulation is near. They are more expensive and are only sold in single packs or up to 10 units.

Analogue test Digital test
Approximate unit price Between 10 and 20 pesos Between 60 and 70 pesos
Readability Can be confusing Very clear
Quantity per pack From 10 to 100 From 1 to 10

How to use and interpret an ovulation test?

In both cases, whether it is a digital or analogue test, a urine sample is required. With the digital test, the urine is deposited on a dipstick which is then inserted into the device. After a couple of minutes, the smiley face or circle will appear.

The increase in luteinising hormone will give a positive result

Interpreting the result with this type of test will be easier because if an increase in LH hormone is recorded, a smiley face will appear on the test screen. If the result is negative, a circle will be displayed.

In the case of the analogue test, the strip must be immersed in the urine sample for several seconds without exceeding the marker line. Then place it on a flat surface and wait for five minutes.

The strips have two levels: the control line and the test line. To know if the result is positive, both strips must be visible. The colour on both strips must be of the same intensity, otherwise it could be a negative result.

Buying criteria: factors that allow you to compare and rate different models of ovulation tests

Before you make your purchase, the more informed you are about the product, the better, because you will know it in depth. Here is a list of factors to consider so that you can compare and rate ovulation tests.

  • Number of tests
  • Sustainability

Number of tests

The number of tests you should buy depends on how often you use the tests. We can divide them into three main groups: those ranging from a single presentation up to 10, from more than 10 up to 50, and from more than 50 up to 100.

Small. We consider a small number of tests if the presentation is individual or has up to 10. This is a good option if your menstrual cycle is regular, as it will be easier to know which days you are most fertile. Most of the tests that come in this presentation are the digital ones.

Medium. This is the most common presentation as it varies from 10 to 50 tests. It is an ideal presentation if your cycles are not very regular or if you are looking for an economical option as the price for the amount of tests included is not high.

Great. If you have been using ovulation tests frequently for a long time, this is an option for you because the price will be even more attractive as the packs include up to 100 tests. The tests that are available in this presentation are the analogues.


Besides the fact that ovulation tests are available in different presentations, there are also different materials to manufacture them. There are more and more environmentally friendly products and this is no exception.

Eco-friendly test. The most common product is the SolCraft brand. It is a great option if you have a preference for sustainable products as more than 90% of its materials are biodegradable and the wrapper is 100% recyclable. It is 99% effective.

Regular test. Conventional ovulation tests do not have biodegradable materials, however, they are much easier to find in shops for purchase. They are also available in analogue and digital formats.
