The 24hr Precept

Caught in the middle
This is one question that is easy to answer, yes ofcourse! But the hard question is WHY?
Why require drug testing? This is to ensure safety of students inside the campus. Also, it sets a standard, that the school is prestigious enough not to accept drug-users. Drugs can cause many adverse effects to the person using it, may it be physically, mentally or socially. It can change one person in many ways. Having a drug user as a student and part of the school isn't a good idea, they can serve as influences to non-users to become potential users, this is in relation to the rampant issue of "peer-pressure." Furthermore, it can be done just as a formality thingy but there's nothing to lose for the part of the school and the incoming students if this is implemented, if you are drug-free why contradict it, right?. :)
BUT WHAT IF IT WAS NOT A REQUIREMENT?
If drug testing isn't a requirement in school, it can also be good in some perspectives. It can give a chance for drug users to go to school, knowing that they will now be apprehended on their choice of being users. People are entitiled to freedom, what if it was their choice to be users? Should they be deprived from learning or going to school? This issue may violate their freedom..
Think about it... Its a very good thought to ponder. Yes, using drugs is bad.. But will you deprive a problematic user from wanting to learn? Will you deprive a user of education?...

Pens up, lets check your answers.
Blood can be used in a wide array of Chemistry studies, as well as Hematological studies.
- FBG
- BUN
- Bilirubin
- Uric Acid
- Testing for Insulin levels
Blood, serum preferred and heparinized blood can be used.
7 & 8. Give 2 other tests that can be used in testing for Insulin levels.
- Fasting Plasma Glucose (FPG)
- Casual Plasma Glucose (CPG)
- Red-topped tube
- Grey-topped tube
Case Study:
A pregnant woman has been complaining of having a problem when urinating. She consulted the doctor and has been suspected to have UTI. She was sent to the laboratory for some tests. Will blood be used as a specimen of choice in her situation? If yes, explain. If no, what is the specimen to be used?
ANSWER: No, blood cannot be used as a specimen of choice in this situation. It is because, she has been suspected to have UTI, and in testing for this urine will be the specimen of choice.

Brain Cells Activator :)
1-5. When can blood be used as a specimen? Identify 5 tests.
6. What is the specimen of choice in testing for Insulin levels?
7 & 8. Give 2 other tests that can be used in testing for Insulin levels.
9 & 10. What are the two preferred collection tubes to be used in testing for Insulin and Glucose tests?
Lets keep those brain cells functioning with this case analysis:

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.......

Answers to Quiz
1. Insulin is a hormone that has effects on the body's metabolism.
2. Insulin stores glucose in the blood as glycogen.
3. When testing for insulin RIA is used to give a quantitative assay.
4. Is fasting required prior to testing? YES or NO.
5. Insulin stops the usage of fat as an energy source.
A -- increased insulin level
B -- decreased insulin level
6. A Insulinoma
7. A untreated Type 2 Diabetes mellitus
8. B severe Type 1 Diabetes mellitus
9. A Acromegaly
10. A Cushing's Syndrome
Case Study
1. Other tests such as OGTT (Oral Glucose Tolerance test), FBS (Fasting Blood Sugar), RBS (Random Blood Sugar) could be used to diagnose increased sugar levels, like diabetes, which is the cause of the positive Benedict's and Fehling's tests.
2. Other tests Other tests such as OGTT (Oral Glucose Tolerance test), FBS (Fasting Blood Sugar), RBS (Random Blood Sugar) could be used to diagnose increased sugar levels, like diabetes. In this specific case, diabetes mellitus is diagnosed from the given laboratory tests.

Insulin
INSULIN
Insulin is defined as “a hormone that has extensive effects on metabolism and other body functions, such as vascular compliance. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle, and stopping use of fat as an energy source.” (Wikipedia 2009)

Testing for insulin is done using a radioimmunoassay that gives a quantitative analysis of serum insulin levels.
Patient Preparation:
- Patient should fast from all foods and fluids except water for 10-12 hours prior to testing.
Procedure and Posttest Care:
- Obtain 5mL of blood from a fasting person, serum is preferred. Observe standard precautions.
- Instruct patient that he/she may resume from his/her usual activities after the test.
Interfering Factors:
- Oral hypoglycemic agent ingestion or injection causes elevated insulin levels.
- Oral contaceptives and other drugs cause falsely elevated values.
- Recently administered radioisotopes affect test results.
- In the second to third trimester of pregnancy, there is a relative insulin resistance with a progressive decrease of plasma glucose and immunoreactive insulin.
- Agitation and stress.
- Hemolysis due to rough handling of the sample.
Reference Values:
NORMAL:
Immunoreactive
Adults: 0-35 IU/mL or 0-243 pmol/L
Children: 0-10 IU/mL or 0-69 pmol/L
Free
Adults: 0-17 IU/mL or 0-118 pmol/L
Children (prepubertal): 0-13 IU/mL or 0-90 pmol/L
- Increased insulin levels:
- Insulinoma
- Type 2 diabetes mellitus, untreated
- Acromegaly
- Cushing's syndrome
- Endogenous administration of insulin (factitious hypoglycemia)
- Obesity (most common cause)
- Pancreatic islet cell hyperplasia
2. Decreased insulin levels:
- Type 1 diabetes mellitus (severe)
- hypopituitarism
