Are Baseline Bloodtests Helpful Later?

[RollingAlong]

I DID ask about the celiac panel, I must have misunderstood...

because after a 3 month gluten challenge (following a year of gluten lite because of very low carb) my husband's blood work shows only an Endomysial which was negative and some other tests I hadn't expected:

WBC 3.2 (range 4.5 - 13)

RBC 3.74 (4.5 - 5.3)

HGB 11.8 (13.0 - 17.5)

HCT 34.3 (37.0 - 49.0)

MCV 91.6 (80.0 - 100.0)

The GI said he didn't now what could be causing these blood #'s and we should f/up with the internist. I'm pretty positive the anemia is resolving; he's much less pale, So presumably the WBC will too.

The endoscopy went ok, but it took awhile to get the results so it has been 2 weeks gluten-free.

Should he ask for more bloodwork at his next appt 11-18?

Is having a baseline helpful to see how it is going with the diet?

is this too long gluten-free for the tests to work?

If directlabs is any good, he could get those tests done sooner. He's never had any positive bloodwork. He has tested postive at Enterolab for gluten, casein, soy and (just barely) eggs.

the biopsy itself was negative, but I don't have the pathologist's report in writing yet and I'm sort of doubtful. I mean, is this doc really on the ball? He's on the list from the local CSA support group and he's very supportive of the diet despite the negative biopsy I'll put the biopsy stuff in a separate post.

Thank you very kindly for any input, suggestions
