When is blood used as a specimen?


When is blood used as a specimen?

Blood is the specimen of choice for most Clinical Chemistry studies, such as FBG (Fasting Blood Glucose), Bilirubin, BUN (Blood Urea Nitrogen), Uric Acid, and the list goes on and on....

Can blood be used to test Insulin levels?
In testing for Insulin levels, blood is the specimen of choice. The blood sample is drawn from a fasting patient, serum preferred and heparinized blood can be used.

In conjunction with testing for Insulin levels, Fasting Blood Glucose (FBG), Fasting Blood Sugar (FBS), Fasting Plasma Glucose (FPG), and Casual Plasma Glucose (CPG) are also done to determine the sugar level status or if the patient is diabetic or not. This is in relation that Insulin is a regulator of the blood sugar level. These tests make use of vein-drawn blood samples which are then placed in a red or grey-top.

Without any need for professional training, one can monitor his or her glucose level in your own personal home with the use of a portable blood glucose analyzer. The test is called Self- Monitoring of Blood Glucose (SMBG) Testing. Blood is still the specimen of choice for this test, but instead of a 5ml blood sample, only capillary blood is needed because it only needs a minute amount of blood. Capillary blood can be attained by doing a skin puncture on yourself with the use of an automatic lancet. Preferred puncture sites include: fingertips(preferred site), forearm, bicep area, palm of hand, and sometimes calf.


What collection tubes can be used to collect the blood for the Insulin and Glucose tests?
Red-topped tube --this contains no anti-coagulants, it can be used to prepare serum

Gray-topped tube --this tube contains potassium oxalate and sodium fluoride, this is preferred for glucose level testing & glucose tolerance levels



**the above photo shows the AUTHOR and OWNER of this blog, who definetely does NOT LOOK LIKE A SPLOG ;P, performing capillary puncture on a patient.




IT IS HARD TO REMAIN SILENT DESPITE ALL THE BAD THINGS SAID ABOUT US, IT IS HARD TO KEEP MUM ABOUT ALL THE ISSUES, SO I WANT TO SAY THANK YOU TO THOSE WHO TRYING TO PULL US DOWN BECAUSE

"INTRIGUES WILL NOT BE SAID UNLESS WE ARE NOT INTERESTING, AND TWO IF THEY ARE NOT WORTH TALKING ABOUT."

SO I GUESS WE ARE INTERESTING AND WORTH TALKING ABOUT HUH? THANK YOU FOR THE ATTENTION. HAHA. SEEMS LIKE YOU HAVE WASTED MUCH OF YOUR TIME ON US, THANK YOU. YOU HAVE JUST MADE US MORE CONFIDENT TO FACE ALL OF YOU IN DEFENSE OF OUR MENTOR. AND FOR THE RECORD, IF SHE FORCED US TO VOTE, THEN WE SHOULD HAVE VOTED FOR HER. BUT OUR VOTES SPEAK FOR THAT. PEACE Y'ALL.





WE STAND BY YOU, OUR MOTHER.......

  3. LOL!! You are all too vibrant, real, and smart to be sploggers. I've known sploggers. They're none of what you are. I love this post, and the pictures!!

    Anjelica, I left you a comment on Random Thoughts, as well.

    I have a question: When is blood NOT an appropriate specimen?

  4. Jehlz,

    We have a great question from Holly for you to answer.

    I know you can give a sufficient answer to this.

  6. Hi Mam Holly. No, please feel free to ask questions. I just needed time to answer your question. So here is my answer:

    Blood is not used as an appropriate specimen when testing for the presence of urinary tract infections, upper of lower. This will not be detected in the blood, therefore it is not an appropriate specimen of choice. Also in Meningitidis, it makes use of CSF (Cerebrospinal Fluid) as a specimen, aside from blood. These are only a few of the specimens that we can make use aside from blood. All body fluids are considered as specimens for laboratory testing. I hope I answered your question well. :)

  7. Yes, thank you, Anjelica! Where most people just think "ewww, bodily fluids?" you see all the fascinating stories those specimens have to tell. On a cellular and molecular level, they're all quite interesting - even beautiful.

    I will be over here cheering you and your classmates on as you continue your studies and Internships.

  8. Hi, Anjelica! Very nice post. ...And I'm referring not just to the substantive part which is very well presented.

    So, you're the one in the first photo who's doing the puncturing thing? Wow, I won't mess with you lest I be shouting "ouch!" a lot. :D

    I don't believe that the people in the second photo are the the Clinical Chem students. They look more like Hollywood celebrities to me. ;)

    Yes, you guys are all interesting. And y'all rock! Take care.

  9. You are very much real Angelica. As real as warm blood extracted and used as a specimen in this post. ;)

  10. What a bunch of lovely splogs - er, young people. It thrills me to imagine all your detractors being lined up to face you in your own turf. I have in mind you're holding a humongous syringe in your hand to take DNA samples of those people.

    Of course, the object of your research is to find out the preponderance or lack thereof of functioning brain cells in that group of people. It's a very much needed research in the interest of mental health in the blogosphere.

    Can they pass the test? Will you find the missing link among these creatures? That to me is very interesting. :)

    You've got spunk. And I love it that you call your mentor your mother. Thanks a lot. :)

  11. just dropping by from jan's blog. parang crash course on fbs. i'm doing this for my mom at home.

    not related to your post but just have to tell you that at this very moment, i am reading the case of naguiat vs. court of appeals for a class recitation. how creepy can that be? well just had to mention that.

    this is a stupid question, but what exactly is a splogger?

  12. hi luke. :) yes sir, it will be hard to mess with us because we can do things normal people can't even imagine thinking about. harharhar.

  13. hi docZ. you are very much real yourself, and infact a good singer. haha. :) just kidding.

  14. hir sir jan. you know what, i think i will be able to find the missing link among them, but it will be hard to alterate bad mutations, don't you think? haha. i'd love to try though, it would be a good challenge for me. :)

  15. sir jan, sometimes i think i was gifted with too much spunk that it gets bad already. :-/ haha. yes, she is our mother. as you saw yesterday, we love her to death. ;)

  16. hi fifi. :) thank you for spending time to read my post. really? what case thingy? there are only a few naguiat's, maybe i am sort-of related to what your reading. haha. a splogger is said to be a non-living organism created only by technology. that is my personal definition of it. :)

  17. Very interesting post. Thanks for sharing it! It is always a joy to learn something that I didn't know. I have you to thank for teaching me something new, and I appreciate it very much. :-)
