Specimen handling

In the laboratory, each blood samples undergoes a multi-stage quality assurance process which prepares the sample for analysis. After completion of the pre-analytical validation, the Alcat Test will be performed.



Functional leukocyte activation test for determining pro-inflammatory non-allergic cell reactions to foods, chemical substances, medicinal herbs, and others.


Stability of specimens

Leukocytes have a life spam of up to 10 days. The Alcat samples can be processed at room temperature for ≥ 24-48h (individually up to 72h).


Restrictions /rejection criteria

Is fasting required before taking the Alcat Test?

No, fasting is not required before taking the Alcat Test but being well hydrated is recommended.

However, direct consumption of meat or highly fatty foods (e.g. some types of sausage) prior to blood collection is not recommended.

Should the blood sample be shipped immediately?

The whole blood sample is time-sensitive due to the relatively short life-spam of the innate immune cells. Therefore, the sample should be shipped immediately, on the day of blood collection, to avoid all unnecessary delays (weather or longer delivery time due to unexpected circumstances).

If this is not possible (Sunday or holiday), the sample should be shipped the next day. Please note that all tests undergo a pre-analysis to validate the integrity of the immune cell before performing the Alcat Test. Usually the sample can be tested 24 to 72 hours after blood collection. 

Do I need to fill each vial to capacity?

Yes, each vial collected must be filled to capacity. The number of vials is clearly indicated on the lab requisition form.

Are there medication restrictions?

It is not necessary to postpone testing despite medication use. If possible do not take any medications 3 to 4 hours prior to blood draw.

Taking medication is part of the patient’s daily life and should therefore also be considered in Alcat testing. 

The situation is different in case of a one-off infection. After a course of antibiotics, the patient should wait 14 days.

Are blood draws possible on FR and SA?

Our regular blood collection days are from Monday to Thursday.

If you would also like to send in blood samples on FRIDAY or plan to pick them up on SATURDAY, please contact us.

One of our courier partners provides special airbills and delivers on Saturdays – and also collects your samples on Saturdays. 

Is there any special handling for the sample?

Blood is collected in the blue top vials provided in the test kit and should be stored at room temperature until shipped. Specimen should not be frozen, spun or refrigerated. Sample should be viable for at least 48 hours.

The laboratory will determine if the cells viability are within specifications for testing.

Does the Alcat Test also test food allergies type 1?

The Alcat Test is NOT a food allergy test. It is designed to test for sensitivities, which have a delayed reaction. Although in common parlance, the terms have been used interchangeably, food allergy and food sensitivity are quite different from one another.

The main difference is that for allergies, parameters of the specific immune system are tested (antibodies), whereas the Alcat Test is a cellular test, with primarily innate immune cells as target cells. – Please note, that these are two very different pathways and may not exclude each other.

However, the Alcat Test detects sensitivities and NOT allergies. The patient should still avoid all items to which he/she has a known allergy.


Should previously reactive foods be reintroduced or consumed before (re-) testing?

Yes, the consumption of previously reactive foods before re-testing after 6 months or foods that the patient considers problematic may set a clear accent before testing.

Foods that are not consumed regularly (provided there is no allergy or coeliac condition) can thus be consumed two or three times within the week before taking the Alcat Test.
