Repeat blood tests - Why?
« on: August 11, 2012, 06:15:14 pm »
I had bloods tests done this week - full blood count and serum ferritin.  To try to find a reason why I'm as tired as a sleepy thing at the moment. 

Just got a letter from the GP and they want them repeating in a month.  I'll be wondering why all weekend now.  Anyone have any idea what they might be looking for?

Funny - very similar thing has happened (is still happening) to me. In my case, I think it's because one result shows inflammation, or something. It's not surprising, because I was under the weather when they did it. I think the retest in 4 weeks is to allow me to get over whatever it is, so the results aren't skewed by anything.

MRsCharly had exhaustion problems - they tested for B12 anf ferritin levels

Repeat in a month might be to see if it results are related to timing in your cycle. But a month's gap seems silly in that case. 2 weeks would be more sensible (unless they want to see if results are reproducable)

Probably borderline abnormal/normal result.
Want repeat after an interval to determine if you'd benefit from eg iron therapy.

If you had *really* low ferritin, they'd put you on iron and maybe investigate for iron deficiency. If your ferritin is low*ish*, they may want to see if if it's stable or changing.

I wouldn't worry; if your results were seriously abnormal, they would act.

Some lab results can be completely out of line with what is expected for a patient. When that's the case, repeats are usually requested immediately.

If they'd lost it, I would hope they'd come clean, explain the loss and request a repeat as soon as conveniently possible.

If you are on a prescription repeat blood tests are often taken to check for any improvements in the results. Quite normal procedure.
