Lab Results 1/16/2020, Part II (updated)

More bad news. Each month, the dialysis clinic tests for dialysis clearance or adequacy. For hemodialysis, there are two measurements: Kt/V and URR (Urea Reduction Ratio).

Test	Limit	Prior Month	This Month
Kt/V	>1.2	1.199	1.0 something
URR	>65%	64.7%	60.6%

For some reason, both numbers have gotten worse. They are drawing blood today to retest. I did not provide a 24 hour urine collection this month but since last month’s 50 mL did not contribute anything to the clearance, I don’t think it will matters this month either.

Depending on the restest, they may ask to increase the dialysis time to four hours per session since they can’t increase the flow rate anymore.

==========

Whew! I just saw the updated test results. It only shows the URR value and it’s 65.0%. I think that meets the minimum requirements. The Kt/V is a calculated number. Since I cleared with a URR of 64.7%, the updated results should yield a satisfactory Kt/V value too.

The super low number was when I was just to switched back to hemodialysis. It’s the result of inadequate peritoneal dialysis. I don’t know about all the other dips in prior results; I wasn’t asked to do more dialysis at the time. Maybe there is large variability day-to-day in dialysis effectiveness.
