SEC S20W2 || Hematology [Hemoglobin - Module 2]

Hello everyone, I hope you all are doing well, I am here to share my participation for Steemit engagement challenge season 20 week 2. As a medical student, I have enough knowledge about this week's topic but if I lack anything please forgive me because I am not expert in it.

Death of Rafael Rangel

He was a doctor and a scientist, and everybody knew he was from Venezuela and he was a parasitologist.

So what was the reason for discussing actually when he died, he was very young, he was just 32, and this was, you can say, his bad experience which ended his life and what was the reason. He experimented while experimenting with mixing the potassium cyanide with wine after getting the mixture of these, which is what he got in the result.

He just drank it, according to some of his colleagues. He was shouting in pain, and his colleagues found him crying with pain. His friends asked what he did you do and then he just told them he had drunk potassium cyanide. In a very short period, he just fainted away, and many people weren't able to save his life.

Later on, there was much research done on that experiment, and then later on, they came to know that the potassium cyanide in his blood was a mixture of something which is called potassium ferrocyanide. That was the cause of his sudden death, so no doubt this was an accident that's of a very young parasitologist, a well-known scientist.

Haemoglobin

So what is the haemoglobin? This is a simple word for protein, which carries Oxygen and carbon dioxide in our body, so if we talk about the structure of haemoglobin, this is made up of 4 chains: 2 alpha and 2 beta chains.

Adult haemoglobin is somewhat different from fetal haemoglobin, but both are made out of chains that carry oxygen from our lungs. This oxygen is delivered through the body tissues to perform their activities, and it gets back the carbon dioxide from the whole body tissues, and then it is through back to lungs and via exhalation its exhale out.

There are many important features of why oxygen is very important for tissues to perform their daily activities and maintain tissue structure cell structures and different energy metabolic activities going on in our body need oxygen. Another important thing is to maintain the pH.

All the proteins and enzymes are working on specific pH so this is important to exhale out the carbon dioxide from the body so that body pH can be maintained and all the enzymes and protein work at there pH to maintain all the metabolic and energy metabolism in our body

Automated Hematocrit vs Manual Hematocrit

So there are two types, automatic and manual, so which one is the best? No doubt we can proudly say that automatically is the best one and what are the reasons behind that? I will try to elaborate on each and every point so you can understand why this is best and what are the reasons.

Automatic hematocrit

So the automatic one is the fastest system and no doubt it is more efficient than any other system because we get the result within a few minutes.

But mainly we use it if we are analysing a large group of samples the volume is very large. So we use this automatic method because there is reduction of human errors. When taking the samples so what we are doing is the possibility of many human error in getting samples and then analysing it. So when the volume is large refer to use, this method.

Most importantly we got so many parameters are analysed in this way. For example , we additionally mean cell volume. We can know the blood cell count and MCV as a doctor. I know what the value of MCV is the prediction about iron deficiency or we can simply say this is giving us the main cell volume so yeah the best method to use is automatically, it is the most fastest efficient quick system.

Manual hematocrit

If we talk about the manual method, you know there are so many errors because first, we are getting the samples. Then there is a possibility of leakage or wastage of the blood while filling it into those tubes, and then with the centrifugation, there is chance of the human error so we prefer actually to automatic hematocrit.

No matter how a patient is it takes around 10 to 15 minutes at least so this is not very fast as well as not very efficient. Another reason is that you know there is a patient with dengue malaria or any other patient and we just in giving the two CC blood and we want to get result.

So for smaller volume we prefer the manual method and we can get the result in 10 to 15 minutes. Another thing why this is mostly used manual method is most commonly used worldwide because this is you know very cheap everyone can afford it and simple equipment is used for getting the manual method.

If we wanted to see the differences, I think the automatic system may be the quickest one may be the most efficient one, but no doubt this is more well used for low hematocrit values.

But we agree that the manual system is the simplest one and cheapest and there is no doubt that this is simply performed by everyone, mainly the technician.

We are using both of the methods worldwide, but as I already mentioned, if we want the larger volumes, if we want to speak to the decision, and if we want to get a more efficient system, we prefer the automatic hematocrit.

Real life example with the concept of hematocrit

So the last question is very important to answer the concept of hematocrit so there is much more significance of this particular thing to know. For example if the patient is anaemic and you know it means that there are fewer red blood cells in the patient's blood or Another condition which is called polycythemia which means that the red blood cells are more.

There is a list of tests we use to diagnose anaemia or polycythemia, but simply if we want to know, then we analyse the hematocrit, and we can know whether the patient is suffering from either condition by just getting hematocrit.

The patient came with rapid breathing rate or feeling lazy or any symptoms, so we simply wanted to know the value of hematocrit and if there is a specific percentage.

So this is a very common test which is worldly use and very commonly used to know certain diseases by just getting no the matter great percentage.

This was all about my participation, I would like to invite my friends @iqrarana786, @m-fdo, @drhira to share their participation.
