First WEek of InternShip

My first week of being an intern at AUFMC, is just like our preceptorship day. We were not yet assigned in our permanent sections in the lab because Ma'am Noemi is on --- leave (sorry, im not allowed to say the word :)) hehe) So we waited until she came and give us our partner and our section. My partner in Phlebotomy section is non other than--Shane! Cant believe that she would be my lab partner for 6months.

At first we were both nervous in extracting blood from patients, but of course we dont have a choice, we cannot endorse every extraction to our staff and the fact that we are there to learn. And so now, on my third week in that section, I'm well adjusted with the works there. We also join our staff in warding, we usually have 5AM, 6AM, 10AM, 8PM, and 12MN hours of warding.

Night duties are the "magastos" duty that we have. Because we usually eat at least 4x from 1PM-8AM of duty. We are lucky if we have 4hrs of sleep, from my last duty I only have an hour for nap time. And always expect that you have loads of specimen in the morning specially when its weekdays. It's not toxic in the lab during weekends.

The staff there are good, we have junior and senior staff. Most of the staff there are former students in AUF, so we share common stories during dull time.

Drug Testing

" Do you agree that drug testing should be done as a requirement for admission to schools? Why and why not?"

I agree that drug testing should be included as one of the tests to be accomplished by an incoming student when enrolling in a university or school.

Let's face it, not all freshmen are first timers in college, some are transferees from other schools. It's a another way of checking the background or personality of individuals.

Taking drugs like marijuana and cocaine which are substances of abuse is not something to be proud of. People using these (for me) are people who have problems and are not capable of handling them.

No one wants to be in a school with classmates who are drug users in the first place. And for parents, they don't want their children to be exposed in that kind of environment. They brought their children to school to learn good things and not to be influenced to the wrong direction.

And if you're the school owner, you don't want your school to be call "School of Addicts", it would be a greatly disgrace if you have students who are drug users just because they want to be happy. So I really agree of drug testing as a part of admission test for an incoming student.



1. EIA (Enzyme Immunoassay)
2. True
3-5. Unknown (antigen), Antibody (enzyme linked), substrate
6-8. Sandwich ELISA, Competitive ELISA, Indirect ELISA
9. True
10. True

CASE Analysis

The doctor might order a test to determine the calcium level in the womans body including the hormones that regulate the calcium.

ELISA is recommended method in determination of hormone levels. Because its a direct measurement, and a very specific method.

CasE AnaLysiS for ELISA

1. Other name for ELISA.

2. True or false: The principle of ELISA is to detect an unknown sample using a specific antibody which is linked in an enzyme, which the antigen will react with, that will be measured directly.

3-5. What are the reagents used in ELISA?

6-8. Give at least three example of ELISA.

9. True or false: Elisa can also be used in measuring hormone?

10. True or false: Can ELISA be considered a confirmatory test?

CaSE AnaLysis

A 60 y.o. woman is experiencing backache, broken bones or fracture, decrease in height, and was diagnosed to have a mild osteoporosis 10years ago. Her doctor gave her already medicines and she started to recover from it. Unfortunately, due to insufficient money, she failed to complete her medications and begun to work as a laundry woman in a rich family. Because the family loved her, they sent her to a doctor and promised to support her entire medication.

What is the possible test her doctor might request for her?

Give one method which can confirm test results.

Enzyme-linked Immunosorbent Assay, as the name implies, it uses enzyme, antigen, and antibody reaction. It is also known as EIA, or Enzyme Immunoassay. It can measure antigen-antibody binding. You can use it in measuring hormones, enzymes etc.

Principle: Unknown antigen is attached in a cell surface, then you will add a specific antibody to which that antigen will react to (you now have antigen-antibody reaction)this antibody is linked to an enzyme. To have a measurement of the antigen-antibody reaction you need to add a substance which can cause the enzyme to produce a detectable signal, like an amplifier. (e.g. Fluorescense ELISA)

There are several types of of ELISA:

Indirect ELISA and Sandwich ELISA

Competitive ASSAY

In relation to parathyroid hormone, ELISA can be used to measure the amount of PTH in our system. As mentioned in the intorduction, it can measure hormones. You can apply any of the severeal types of ELISA procedure. ELISA kit are now available in the market for easy use.

The video is short, yet it gave you a background on how the parathyroid gland works.=)

The parathyroid gland/s are small but it has a major role in our system that cannot be neglected.

aNsWeRs to Parathyroid gland quiz

1. An individual has 4-6 parathyroid glands.
2. To secrete parathyroid hormone that regulates the calcium, magnesium and phosphate in our system.
3.4. The chief and the oxyphil cells are the cells commonly found in the parathyroid gland
5-7. The parathyroid regulates the secretion, excretion and absorption of calcium, phosphate and magnesium in our body.
8-9. Hyperparathyroidism & hypoparathyroidism
10. The parathyroid gland is located posteriorly in the surface of the thyroid gland.

CaSe AnaLySis

Case 1
The probable condition of the old woman is osteoporosis. Osteoporosis is characterized by having a fragile bone because the bone has loss its normal density. And people having osteoporosis have a high risk of bone fracture. Common symptoms of osteoporosis are fractured bones (can be in spine and in hips) and lower backaches.

Osteoporosis is routinely diagnosed by x-ray. X-ray reveals that a bone having an osteoporosis is much thinner and lighter compared to normal bones, but the disadvantage of x-ray is that it cannot detect early stages of osteoporosis. So, for better diagnosis the National Osteoporosis foundation and the other major medical organization recommend- DUAL ENERGY X-RAY ABSORPTION SCAN (DXA, formerly known as DEXA).

It only uses small amounts of radiation and it measures bone density in the hip and in the spine and compares it to the average bone density of an adult of the same sex and race. It is measured using a standard deviation.

Factors that have a high risk of having osteoporosis are:
  • females
  • thin and small body frames
  • personal history of fracture as an adult
  • family history of oasteoporosis
  • diet low in calcium
  • cigarette smoking
  • poor nutrition
  • no exercise

Case 2


As the name implies, hyperparathyroidism, is an excessive secretion of parathyroid hormone by parathyroid gland.

The common symptoms of hyperparathyroidism are:
  1. you feel nervous, moody, weak or tired
  2. have hand tremors
  3. sweat a lot
  4. loss weight
Too much parathyroid hormone can cause complications. Some of its underlying conditions are:
  • parathyroid adenoma
  • parathyroid hyperplasia
  • parathyroid cancer
  • kidney problems(kidney failure)
  • familial endocrine neoplasia type 1
As said in the case, Angelo, have developed underlying complications. He developed kidney problems, caused by his hyperparathyroidism.

The usual scenario of hyperparathyroidism is, the balanced is disrupted. The blood calcium levels increase (hypercalemia), which may indicate that there is problem in the px parathyroid gland.

The common cause of it is family history with the said disease. Common ways to diagnose is by measuring PTH in the blood sample of the patient. And because there is too much calcium in the system, bone density can be checked too.

The simplified solution for this is the removal of the enlarged parathyroid gland, even if your parathyroid gland has been removed, it can regenerate again to produce a new parathyroid gland.

Parathyroid Gland (Ana Physio)

The smallest Endocrine Gland.

The Parathyroid gland is located posteriorly in the surface of the thyroid gland. Usually, an individual has four to six of it, 8 being the greatest number.

Its main cells are:

a) parathyroid chief cell

b) oxyphil cell

These cells are spread through out the parathyroid gland. They are packed closely to the capillaries, which differentiates this gland from the thyroid gland.

The major role of parathyroid gland is to secrete parathyroid hormone. This hormone is the major regulator of calcium, phosphate and magnesium in the blood.

It increases the blood’s calcium and phosphate by bone resorption. As the values of calcium and magnesium increase, the PTH acts in the kidney by excreting the excess amount of Ca2+, and Mg2+ in the urine.

This process also applies to the values of HPO42-, it also decreases its concentration in the blood through excretion in the urine.

Another role of PTH is to secrete calcitriol, which is the active form of Vit. D. It is also known as 1, 25-dihydroxy vitamin D.

The role of calcitriol is to increase the absorption of calcium, magnesium and phosphate in the gastrointestinal tract.
