Just got the results of the 2nd test and the tryptase level was still 18.
Then the level of 18 is her baseline, which is high but not super high.
So the doc put off the followup test for 4 weeks to see if the elevated trypsin is transitory and will go down by itself. Was she having bad hayfever or other allergies at the time of the test? You want her to have a low baseline even if she has big spikes.
Btw, I've read that children can have a problem with MCs but that it can get better all by itself over years, so keep your fingers crossed for that, too.
She can observe if any foods trigger any symptoms, and of course then avoid those foods.
The red line (dermographia) happens because MCs in the skin get set off too easily. It's not normal. You can try drawing the line on yourself and compare what happens to hers. This is likely a genetic condition. Any blood relatives of hers can test themselves and see if they have something similar.
Make sure that you don't get the followup test soon after a flushing episode. They want a baseline number for the tryptase, when things are settled down.
Be wary of anaphylaxis. I'm not saying that's likely, just that it's possible. One day she *might* have to carry an EpiPen.
I assume rhat she doesn't have mottled reddish brown skin all the time, else you would have mentioned that.
Hi, that sure seems like a problem with "mast cells" aka MCs. A person's MCs produce histamine, which is the chemical that everybody knows is associated with allergies. MC's also produce many other chemicals, such as tryptase, that along with histamine and other MC chemicals are associated with flushing of the skin -- because they dilate blood vessels.
MCs are filled with those chemicals and stay in the skin, waiting to be triggered. In a person with a mast cell disorder, the MCs get set off too easily. E.g., she can probably draw a reddish line on her sternum just by using a fingernail.
It's very possible that her MCs are also causing the severe headaches. So the good news is that by getting diagnosed, a lot of present and future problems can be lessened. But probably not cured per se.
MCs also line the lungs and digestive tract and can cause problems there.
The terms are Mast Cell Activation Disorder (MCAD) and Mast Cell Activation Syndrome (MCAS).
There are some drugs that are "mast cell stabilizers". Good news is that some extracts from plants can do as good OR BETTER than drugs, as shown in studies. You can get them in capsule form. Let me know if you want their names.
Does she happen to be double jointed? There is an association.
There are some serious conditions that can come from MCs, but those don't seem involved here.
And CBC was normal which is good.
