I would not worry about these labs. They are inconsequentially different from prior.For your information - Creatinine is a measure of how well the kidneys are working. We worry more about kidney injury when it is high. BUN is not as specific and should be interpreted in the context of your creatinine. Your CRP is basically unchanged.Your rheumatologist would likely go more based off your symptoms in adjusting your meds, they are probably monitoring side effects of methotrexate so looking at blood counts for signs of low counts and liver function tests. Methotrexate is cleared through the kidneys so if there was a major change in your creatinine it may prompt a dose change. CRP and ESR are inflammatory markers that will be trended.Hope this helps!
Blood work off after MTX. Should I hold the next dose until Rheum consult?30F non-smoker 147 lb 5ft 2in tall, years long history of rheumatoid symptoms and indicative blood work. My degree is in clinical nutrition which means unfortunately I understand the basics of my blood work but am not sure what to do with it. My rheumatologist is out for a week.After 7 weeks of 10 mg oral methotrexate weekly with absolutely no contraindicated medications (sulfa, alcohol, etc) my blood work has come back. I'm just hoping for clarification on if these results are expected with methotrexate, or if I may want to hold a dose until Rheumatology is back in office next week.Creatinine has dropped to 0.51 and was 0.70 prior to treatment. BUN has risen to 24 and was 17 prior to treatment. CRP at 1.4, was 1.3 prior to treatment.If I can ask for any input just to ease my mind, I'd really appreciate it!
