I just noticed that a Comprehensive Metabolic Panel was done on blood samples from 1/16/2020 and 1/24/2020. I don’t know how much results should vary from week to week but here’s a comparison of a few tests:
| Test | Normal Range | 1/16/2020 | 1/24/2020 |
| Albumin | 3.6 – 5.1 | 4.3 g/dL | 3.9 g/dL |
| Calcium | 8.6 – 10.3 | 8.7 mg/dL | 8.9 mg/dL |
| Potassium | 3.5 – 5.3 | 4.8 mmol/L | 5.9 mmol/L |
| Urea Nitrogen (BUN) | 7 – 25 | 33 mg/dL | 29 mg/dL |
| Glucose | 65 – 99 | 172 mg/dL | 100 mg/dL |
| Creatinine | 0.7 – 1.3 | 9.71 mg/dL | 7.91 mg/dL |
| eGFR (non Afr-American) | > 60 | 6 | 7 |
Even though both test results were called Comprehensive Metabolic Panel, some of the items tested were different. I’ve left out a bunch of stuff that were within normal range on both days. Parathyroid Hormone and Hemoglobin A1C results from 1/16/2020 were separate tests outside of the CMP tests. The one result my cardiologist was concerned about was the high potassium number, which was normal a week ago. I wasn’t fasting on either of the test days so not sure if that matters. On 1/24/2020 I had a piece of bread plus a cup of almond milk for breakfast, and there was no food log from 1/16/2020. Another difference was the sample from 1/24/2020 were taken right after cardiac rehab, and exercise may increase potassium levels in some people by 0.9 mmol/L.
The glucose number was high on 1/16/2020, but typically my results are much lower while fasting. Most sources have 70 – 130 as normal for diabetic patients while fasting. Finally, the creatinine and eGFR numbers are way off since the normal ranges shown are for non-ESRD people. Interestingly, the sample from 1/16/2020 were taken prior to dialysis on a Thursday, and the 1/24/2020 results were taken on a Friday, basically a day after dialysis. Looks like dialysis does clear some creatinine but poorly compared to a regular kidney.
