Creatinine

Chloe was recently diagnosed with a kind of hypothyroidism called "Hasimoto's disease", and at more or less the same time, that there were some potential problems with her kidney. The hypothyroidism was a clear diagnosis and she is now ramping up on levothyrox, which has been very effective. The kidney problem (if there is one) hasn't been diagnosed or treated yet because we were hoping that it would go away with the thyroid medication. However, the first round of blood/urine tests showed that there were still some irregularities. One thing that they needed to test for was creatinine levels. When Chloe picked me up from the airport yesterday, she immediately, and with great glee announced that there was a jug of pee (HER pee) in our refrigerator, and not to confuse it with anything else. It turns out that the test for creatinine requires that you collect all of your urine during a 24 hour period. I have to admit that I very indiscreetly asked whether refrigerator storage was completely necessary, for which I was sternly reprimanded. I guess you don;t want the creatinine breaking down any further... or something.
