I don't post often, but I read a lot of posts. I have been reading yours intently b/c of what we've been going through here on the east coast w the Celiac Center in Maryland. We are also FTT, we're waiting on several tests results, although the first set for CF, thryoid, kidney are all negative.
This is going to sound really lame maybe, but I ask b/c sometimes it is as simple as more calories and sometimes no one else as asked... But read through to the bottom of my post b/c I was given very good instructions for putting weight on my baby by a really nice female GI doctor.
Are you sure she is nursing long enough and really getting enough? The first thing anyone should have suggested really, also the hindmilk versus foremilk that causes bowelms to be very different. This is as far as I got into finding out what was wrong with one of my children while nursing, 3 years later it was confirmed Celiacs.
Have you gone to a LC who should have you weigh your child (clothed is fine for this test), feed baby and weigh baby again? The difference between weighings give you a very good approximation of how much the child is gaining from the breast. I did this most recently in the hospital, even though they really wanted me to pump and feed.
And if it isn't a calorie issue, more likely a malabsorption issue then blood tests would indicate this the prealbumin and creatine are very good for this and usually over looked b/c docs look for Vit D, Vit K and Iron as malabsorption signs and skip over the little signs.
I have just gotten back with a FTT child from the hospital and Celiac tests have been done. The biopsy was done last week. We were admitted to the UMMC b/c my child had dropped about 10% of his body weight in less than 2 weeks. At first they wanted to put an NGtube in to feed him, I held them off by saying, he can eat, lets let him eat first before doing anything so drastic. But it sinks in the seriousness of a baby who fails to gain weight and then drops, my baby's head stopped growing too.

What was suggested to me and it is what I am doing --
I am pumping and adding Elecare powder to my breastmilk to give it more calories. I was asked to feed 3oz of bm fortified w 1/2 scoop of powder every 3 hours. I am gluten-free and df. The hospital tried to give 24 calorie Enfamil even though I said my child would not tolerate it. It was promptly thrown it up all over the nurse who fed it while I stepped out for some food! Thankfully it happened to staff and not to me, mother's have no credibility in the hospital as to knowing their child...
I am also nursing to maintain a good supply, pumping alone will eventually cause a drop in supply. I have on order a SNS so I can ditch the bottles for feeding the EBM.
Neocate and Elecare are the ONLY ELEMENTAL only formulas. The doctors tried a semi-elemental which is still derived from dairy and my baby just didn't tolerate it well at all. Pregestimil is for malabsorption, but it caused watery stools after I returned to gluten-free. Confused I insisted a change to an Elemental formula.
You can call Neocate and get a sample or two sent to you if your doctor makes the request for you, if your doctor wants you to feed this formula, I would call and arrange for the free samples -- it is very pricey.
Bottom line weight gain is needed, growth is needed, head growth halting in our case is serious business b/c of how rapidly the brain developes in the first year of life. I'm not a fan of formula, it's never touched the lips of any child before this one. But I also know he needs to make up for his loss more quickly to prevent long lasting effects of his weight loss and head not growing for 6 weeks.
IF my child failed to gain weight under the protocol we are on right now (fortunately thus far I'm seeing gain),
I would not hesitate to give straight Elemental Formula as a trial to see if my child began to thrive (I would pump in the mean time to maintain my supply in the event it didn't work or I decided to give bm a try again). There are times of medical need where formula is not a bad thing, it's original purpose was to aid a FTT baby that belonged to Mead Johnson! The start was not out of malicious intent to over come the world and sway moms from breastfeeding, even if that is what did happen.
I hope you get some weight on that baby, even if you don't find out now what's going on, you little one needs you to help her grow in anyway that makes that possible. I say that from my heart having had the same delima and weighing the options of what I could do and what I needed to do for my baby.
I have some resources for "fatting" up bm if you're interested. I'm trying them, but from what I'm pumping I see very little fat. I'm a skinny milk producer!
Did I read you were gluten-free having the Celiac tests done? I would not redo them now b/c right now your child is critically in need of gaining weight. I'm honestly surprised you are not in the hospital. I will say that from experience with my older Celiac child, gluten messed up his intestines so badly that he reacted to every major food allergen out there. Once his intestines healed, he was able to eat most foods again, even raw dairy, but not pasteurized.
Keep updating, I pump and spend time on the internet now!
