What is egfr blood test?

Are you curious about the mysterious acronym that your doctor keeps mentioning- EGFR? Does it sound like something straight out of a science fiction movie or perhaps an alien language?

Well, look no further as we delve into the details of EGFR blood test and all its quirks.

Intro to EGFR

Before jumping into what this bizarre term means, let’s take a step back and explore some biology basics. Basically, we’re talking about kidneys (bear with me). Our kidneys are our body’s filtration system where they filter extra water and waste from our blood. So far so good, right?

Now, hold on to your beanies because here comes the technical part—the filtration process occurs in small structures inside kidney called glomeruli at around 200 L per day! That’s equivalent to drinking 800 cups of coffee daily if you need a point of reference!

The EGRF test measures whether your kidneys are functioning properly by measuring how much fluid is filtered through those tiny filaments mentioned earlier.

Why Should I Learn About This?

Great question buster! Knowing more about EGFR can help one understand their overall health status especially when it comes down to sorting out any underlying problems such as diabetes or hypertension. These ailments could put their fancy feet in harm’s way – pun intended – (‘Who knew maths would actually turn out useful?’ she said looking smug).

So sit tight while we spill the beans about everything there is know regarding red flags for your fish-like (“Sorry just wanted to include another aquatic creature simile!”) features hidden behind intriguingly long Greek words.

Kidneys: Are They Okay?

One needs not be Sherlock Holmes plus Aquaman wrapped up together (‘now that would make quite an anime show’) in order examine one’s pee stream output frequency – making sure they’re frequent instead being a little too much like the Sahara at noon (‘okay we’re done with the comparisons now, for real’).

If that doesn’t suffice, a visit to your GP or other medial professional is what you need to ensure whether their kidneys currently are working as expected– otherwise known as diagnosis. After analysing urine sample alongside completion of glomerular filtration rate (GFR) and serum creatinine levels tests (‘we all love an acronym!’), they can start painting a clear picture of where those kidney pals stand on matters health-wise.

So What Exactly IS That EGFR Test?

Hold up folks – there’s more to this than initially meets the eye… Actually not really but just hear me out(‘see?’). Estimated Glomerular Filtration Rate being quite mouthful so we’ll just stick with abbreviation from here onwards- EGFR!

The test examines your blood for Creatinine which is formed whenever muscle cells breakdown—sounds kind of morbid when I put it that way but let’s get serious (‘It was Craycray in lab’). Kidneys filter creatinine out of our bloodstream since higher than average levels indicate lower functioning kidneys; specifically measured using millilitres per minute per 1.73 square metres (ml/min/1.73m²) which–and this should go without saying–is slightly less legible if you’re forced into reading whilst driving along bumpy roads(“Seriously don’t do it! Bad idea!”).

What Can We Learn From Its Results?

  • If Your GFR Is Above 90 ml/min/1.73 m²: Everything appears be firing on all cylinders within little blood filtering organs tucked away neatly inside deep in our stomachs!
  • Between Establish Ranges such As Teetering Just over ‘60’ And Under ’89’: No immediate concern Need keep watch potential developments.
  • A Score Below ’60’ – Indicating Damaged Kidney Filtration: Serious indications of need for further assessment and treatment.


Congratulations- you are officially EGFR experts now! (‘The good kind not like the fake expertise one pretends to have whilst playing Jeopardy-”); You know what the test is, how it works, and even how to interpret its results. So next time your doctor brings up that alphabet in a plastic vial for testing – we’ll bet (not literally) you’ll be more prepared than ever!
