What is gfr in blood test non african american?

Have you ever wondered what the heck people are talking about when they mention GFR in blood tests? Unless you’re a medical professional, this term may as well be Greek to you. Well, fear not my non-African-American friend! In this article, we’ll break down what GFR is and why it’s important for your health.

First things first: What does GFR stand for?

GFR stands for Glomerular Filtration Rate. If that doesn’t make any sense to you, don’t worry – it didn’t make sense to us at first either! Here’s a rundown of some fancy terminology:

  • Glomerulus: A tiny filtering unit found in the kidneys
  • Filtration rate: How fast blood is filtered through those little glomeruli

So put them together and voila – Glomerular Filtration Rate!

Why should I care about my GFR?

Your kidneys have an important job of flushing out waste products and excess fluids from your body. Your GFR number can help doctors determine how well your kidneys are functioning.

A low GFR score means your kidney function might not be so great which could lead to further medical problems like kidney disease or even complete failure of these bad boys (not good).

On the other hand, if you’ve got a high GHR score then go ahead bragging rights because congratulations – your buddies will envy your amazing kidney power

If there’s a chance that this all sounds way too serious let me tell ya… It IS serious but before we dive really deep into seriousness let’s take a moment appreciate something WICKED COOL.

This table contains various examples of famous fictional characters who’d fall on different ranges depending on their age, sex, and race.

Example Character Age Sex Race/Ethnicity Ranges of GFR
Mickey Mouse 92-ish years (est) Male Mouse-American 37-57 mL/min/1.73 m2
Morticia Addams \~45 years old @ time of sitcom airing (maybe she’s eternal?) Female White-American 80 – 120 mL/min/1.73 m2
Lilo Pelekai 11 years old Female Hawaiian-Alean 90–166 mL/min/1.73 m2

[Disclaimer: It’s always best to consult your doctor if you’re concerned about your kidneys.]

How is GFR measured?

There are actually a few different ways that doctors can measure your Glomerular Filtration Rate.

Serum Creatinine test:

This is the most common method for estimating GFR because creatinine is produced by muscles and it passes into the bloodstream where it collects until being filtered out in the kidneys.

Thankfully this test involves only a needle prick (fun!!!) + urine sample assessments to check levels against comprehensive charts which take into account things like age, weight , sex etc…We told ya there’d be some science 🤓

The equation goes something like this

eGFR = K x [(sCr x M/F)/(72xBSA)]

Just kidding could we get any more confusing than THIS? Sure but let me bring you back down from heart palpitations…

More tables! Let’s have a closer look at how different races affect normal measures:

||Normal Range for non-AA Adults  MoAAN Mean +/- SD||
————— ——————-
Age <19 >60

Ages
Ages
|GFR Range (mL/min) |44-130   | for Adults

It’s important to note, though, that GFR ranges can differ based on sex and age…oh speaking of which check this out:

This is wild – the formula itself changes based on your race?! Yas!!!

If you identify as Black or African American then medical wizards use a different equation to determine normal range that includes Ishihara correction factors rather than the ASTM/IDMS-one.

The Takeaway:

Your Glomerular Filtration Rate gives your doctors some dental floss with which they measure how regularly -if at all- urine flows while touring through kidneyville. It helps monitor renal organs functioning correctly AKA operating like little superheroes inside ye olde body. Now anytime someone mentions GFR you’ll be able to throw down knowledge like it’s nobody’s business!
