Lab results, I'm worried

[Elvia1023]

Some of the replies a bizarre. You were dehydrated and have been on those medications. Carry on as normal (you're now off those medications) and get retested in 2 weeks but make sure you are hydrated (take a few days off training as well) and I bet your numbers look good if they have been in the past.

Undoubtedly there was some level of insufficient hydration at play. You can get a pretty good picture of your hydration status (estimated osmolality) if you have your sodium and glucose levels at the time of the draw. Share that if you have it.

Plug your numbers in this calculator to determine your estimated osmolality. It's a helpful indicator at the time of your labs if you was sufficiently hydrated. Above > 295 mOsm/kg, is suggestive of insufficient hydration.

Osmolality determination- Osmolality of blood increases with dehydration and decreases with overhydration. Normal range: 285-295 mOsm/kg

I wouldn't worry at all

I got my testing done after not feeling 100% for a few days. My eGFR came back at 50 and all the other numbers like yourself were jacked up.

Went back 5 days later, did my test mid day (2pm vs 7am fasted) after about 3L of water (I didnt measure, just drank my normal amount) and my eGFR came back at 67.

Like mentioned, throw in the cystatin-C just to be sure but more than likely this sounds like a hydration issue.

My glucose was 98. The range is 70-99 (mg/dl). So it was within range just barely. My sodium was 138 the range is 136-145 (mmol/L). So it was within normal range.

I put it in and I was 296.4. So probably like you guys said dehydrated. When I peed in the cup it was really yellow. Most of the time my piss looks like water.

I realized I didn't put in the right values. The Lab used (mmol/L). On that calculator they use (mEQ/L). So when you put in 138 mmol/l and convert it to mEQ/L. My Osmolality was actually 572.4. So I must have been really dehydrated.

Nice!!

This should be pinned as a thread !!
Great tool !!

Too many unjustified scares from inaccurate interpretations based on potential dehydrated scenarios.

I agree this is a nice tool. You just have to make sure you convert whatever value your lab uses to mEQ/L that is used on the calculator to get the right reading.

Hey Stewie he should get a 24hr clearance test to show true GFR am I right?
Or is there a better test to get?

Well damn that's good to know, never seen that calculator.
My last bloodwork I was 286.9

Gotta bookmark that calculator

Creatinine clearance will only show an estimate. There's strengths and limitations with pretty much all measurements to determine GFR. Inulin injections to measure GFR is considered a gold standard of determining a more accurate GFR. A nephrologist is truly the best option.

You had me at corrected calcium calculator. This is an outstanding tool.

Yeah, variances in albumin levels can change the concentrations of other constituents, i.e., endogenous and exogenous hormones, drugs, enzymes, ions, ect.

 

[pickapeck]

One thing that is confusing to me is that my MA/CR ratio is normal. Which from what I read means normal kidney function. But according to the Creatinine and eGFR as well as my BUN are all high which indicates a problem. Maybe someone on here can interpret that all better than I can. I'll wait to see what the doc says.

It means you're not spilling protein in your urine.

i just had to prevent a new crit care doc from ordering high dose calcium replacement last night because no albumin had been checked in days. A little teaching moment for the new doc when the albumin came back critically low. At least it was well received.
