Yes, S has had fluctuating numbers as well...
During the week he was inpatient, when he was diagnosed, his sed rate (ESR) was taken four times - 26, 63, 53, 43. After being on EEN for six weeks - 9. Over the next 1.5 years, while on supplemental EN only, it ranged from 4 to 35 (some of these were when he had a flu, hockey injuries, etc.). Over the first six months on remicade, it ranges from 2 to 33. GI no longer tests ESR, uses CRP instead. Also, there wasn't always a direct correlation with CRP, even though they are both inflammatory markers. CRP is a more immediate indication of inflammation, ESR takes longer to rise and to lower.
As a reference point, his GI wants his CRP to be below 5. Since being on remicade, it has fluctuated between 0.2 to 2.9 - so again, fluctuation - not a straight line up/down, just up one test, down the next.
Re liver numbers, not sure if you're referring to ALT (normal <50) and AST (normal <36), S has also had fluctuating numbers - however, they have been consistently in the normal range since starting remicade. But, before remicade, within one six week period, they jumped from ALT 61 to 100 and AST 43 to 62. There was no reason to explain the jump, no sickness, no new meds, etc. And, with no treatment for it, they just dropped down to normal levels even before starting remicade.
So, absolutely keep an eye on them, yes GI will know when they are of concern (although I kept my own records and specifically questioned when numbers were off) but numbers do fluctuate and it's not always an immediate concern. :ghug:
