There is a simple device called a pH meter which can be used to measure acidity or alkalinity.
a test strip that tests the acidity or alkalinity level of a liquid.

It is a blood test that determines the level of antibodies (immunoglobulins) in the blood after specific foods are eaten
A STAR Test is an online test that determines your reading level equivalency and the like.

The A1C test is a blood test used to verify the blood sugar level. If the test shows that the blood sugar level is above 120, this determines that the person is diabetic.
A pH test can be conducted to determine the acidity or alkalinity of a substance.
The test that assesses the level of oxygen and carbon dioxide in the blood is called an arterial blood gas (ABG) test. It provides information about the acidity (pH) and levels of oxygen and carbon dioxide in the blood.
Nitrogen oxide gases are typically acidic in nature, so you can test their acidity using a pH indicator paper or a pH meter. Simply expose the gas to the indicator paper or insert the pH meter probe into the gas sample to measure its acidity level. The lower the pH value, the more acidic the nitrogen oxide gas.
pH determination is a test for acidity/basicity.
They can test the soil for its acidity and alkalinity and either correct the pH level or grow plants that are appropriate. They can test the levels of nutrient in the soil and add appropriate fertilising material.
You can test it with a strip of the stuff you use to test pH levels
