“KEEP IT WARM” Blood Draw & Lab Technique

CADs that have become more Reactive to cold Temperatures than a normal person often progress into needing a special blood test method of collection and Lab cooperation.

In this group the Standard Protocol for CBC/RBC Tests may start failing often, or fail all the time.  It has to do with the Agglutination/Clumping of Red Blood Cells when the blood is removed from body temperature.

Initially the patient may experience hit and miss CBC/RBC tests that fail or are inaccurate.  Where you as a patient have to give another sample and they test again.  You may not suspect what is going on yet.  Not tie it to the possibility you are becoming more cold sensitive.  Your Dr may not even be aware, let alone the blood facility techs or Lab personnel, you are being tested through.

If you have moved into this group of CADs.  The CBC/RBC blood specimen will start requiring special handling to produce consistent, accurate test results.

CADs, in this scenario,  may eventually require a “Keep it Warm” process performed all the time.

The specimen tubes must be pre-warmed, the drawn specimen kept warm, and the lab testing done stat.   Ideally at body temperature 98.6°F/37°C.

Reheating the specimen in the lab may or may not work.

Your particular Medical Care Providers, Phlebotomist, and or lab, may or may not be up to speed on any of this?

Satellite specimen collection where the sample is later shipped to a lab, reheated at the lab later, may not successfully result for the CBC/RBC.

We must mention; “keep it warm” is another CAD Patient made up term used by many CADs.  But to our knowledge it is certainly not an official medical term.  So if you start throwing that term around at a blood testing facility or ER room, you might encounter a blank stare.   You will  have to explain.  Expect to be met with doubt.  Having written documents explaining this will become most helpful.

This “Keep it Warm” technique will often be talked about or recommended on CAD types of social media or support forums.  Perhaps your doctor will  know enough to advise you?  If they are familiar with CAD, they will most likely explain this to you.

Once you are in this scenario.  It’s best to have written and signed documentation (By your Dr on their letterhead) detailing the steps to the “keep it warm” technique.  Carry this with you to present at any blood facility, ER Room etc.  Believe me, it will prove invaluable to you.  It will prevent lots of conflicts or even being disbelieved, looked at as a problem person, etc.  Ultimately the goal is, it will eliminate multiple arm poking for re-doing the test.  To also get you an accurate result.

When this Keep it Warm process is not followed on the CADs at this cold sensitivity level, the CBC/RBC will often fail to result, or have invalid numbers.

Note:  Often patients newly identified as having CAD, are already in this stage.

Some CADs may never have had any previous health symptoms to trigger any type of blood testing when they were healthy and not troubled by CAD.
