Erika called me a few days ago with amazing news. Jacob’s blood test results came in. One test determines the levels of various branched-chain amino acids in Jacob’s blood. These amino acids, which include isoleucine, leucine, and valine, come from the natural protein he takes in through carefully-measured amounts of breast milk. The test helps us to know that Jacob is getting adequate nutrition and that his body is processing the breast milk well. The other test is a comprehensive metabolic panel, which gives us more information about his liver and kidney function, among other things. Erika says that not only were his levels for both tests normal, but for the most part they were right in the middle of the normal range. She called Jacob an overachiever, and I couldn’t help feeling so proud of this little boy chattering happily in my arms.
(One exception: His citrulline, as expected, was high. Normal range is 4-50. His was 1635. Yikes. But, that is to be expected given his diagnosis of citrullinemia.)
In other news, Jacob is starting to learn to grasp and shake a rattle. See, Erika was right, he is an overachiever. So proud of this little guy!
