Blood test results high RBC and Platelets (ankle, cold, biopsy)

[Adriank7]

The range on this one and several places online show I’m high. My mother’s and friends Dr has a a higher range which would show I was normal. Why do labs have different ranges? Should I be worried? Just got results and dr isn’t in today. .

Use the range that your lab gave you. You can't compare results from different labs, as they all use different reagents, equipment, and techniques and so give different results.

OP: What hit me right away is your just about Empty Vit D "tank"...I thought mine was pretty bad back in 2006 when I came in at 16.

My last RBC came in at 4.26
Platlets 265

Different labs have different ranges to a small degree I guess.

All labs need to establish their own reference ranges. It's what they do for a variety of reasons, mainly for what oldgardener stated above, but also based on populations in the area. Those numbers are barely out of the references ranges. On a side note, that lab has the lowest reference ranges for platelets I have ever seen.

I have a consistently high platelet count of around 450. That's above normal but not crazy. I also have slightly higher than normal RBC. In my case, they did a whole lot of additional testing, all of which came back normal. However, a high platelet count can be due to inflammation or something like that and I do have a joint issue that causes my ankles and wrists to be sort of randomly inflamed (this is due to joint damage from taking a fluoroquinolone antibiotic for a week - don't even get me started on that).

The platelet count has been stable now for years but definitely on the high end - just not so high that it warrants a bone marrow biopsy or whatever. They finally just shrugged and said, "Well, you feel great and it's not increasing - go forth and prosper." Well, they didn't actually say that but they did say the only possible explanation they could find is that I have some inflammation and the high platelet count is a reaction to that.

Neither of your counts seems excessive though they are a little on the high side. No, I wouldn't worry. Just ask your doctor if you need any additional tests.

Thanks. What was your RBC count?

I was reading that a high RBC count can cause blood clots.

My Dr hasn’t responded. I’ve emails twice and called.

I honestly don't remember. Sorry. It was a little high but they were more concerned about the higher platelet count. From what I recall, either one can increase the risk of blood clots.

You know what they told me? Take 1 baby aspirin a day.

Stone cold normal results.
