Be careful! If there are these 3 arrows in your blood routine report, be alert to leukemia!

Last night, I dragged my tired body

Getting ready to leave work

Ah Wei at the next workstation suddenly jumped up and shouted

"Nosebleed..."

Good boy!!! What are you looking at???

Suddenly

I jumped up from my seat

A clear mind

Eyes as big as bells

Run to his workstation

Righteous words——

Just as I was about to kill my relatives for the sake of justice

When he cleanses his soul

The message he shared came to my phone.

I picked up the teacup and took a sip

Prepare to open the link with trepidation

(Don't misunderstand, I'm just sacrificing myself to keep the evidence to report him)

I was dumbfounded.

OK! It's his baby who has a nosebleed.

I am the social dead! I am the clown! I am the embarrassment!

I'm lost and I'm turning to leave

He suddenly grabbed my hand with a crying voice——

My baby had nosebleeds twice this week.

I just had a blood test yesterday.

White blood cell count is high

Is it leukemia?

I rolled my eyes at him.

You’ve watched too many Korean dramas!

Are you scared to death when you see an arrow?

No need! Mainly look at the 4 major indicators for abnormalities

After receiving the routine blood test report, my parents, who are completely new to medicine, understood every word, but when they put them all together, they couldn't understand any of them.

The only things I could understand were the arrows behind each indicator. As soon as I saw the arrows, my mind collapsed and I felt like the sky was falling.

After all, blood disease is an unbearable burden for every child and family.

But there is no need to worry too much! Don't add drama to your blood test report.

The correct way for a medical "novice" to open a blood test report -

01

At a glance: Which indicators have arrows

A routine blood test report usually contains more than 20 examination items.

Indicators with arrows, which we generally understand as "indicator anomalies", generally require attention:

↑: represents exceeding the upper limit of the reference range;

↓: Indicates that the lower limit of the reference range has not been reached.

02

Second look: Are there any abnormalities in the 4 major indicators?

For most children, the most commonly used and important primary indicators are mainly the following four:

White blood cell count

Red blood cell count

Hemoglobin

Platelet count

If there are no arrows in these four items, generally speaking, there is no major disease and you can just take the medicine as prescribed by the doctor.

However, the fact that these four items have arrows does not mean that you are in big trouble.

If one or several indicators have arrows, it does not necessarily mean there is a problem; even if there is a problem, it is not necessarily a big problem. (See below for the solution)

For parents, the most intuitive indicator is hemoglobin, which can be used for anemia screening.

According to the diagnostic criteria of the World Health Organization, children aged 6 months to 6 years with a hemoglobin concentration of less than 110 g/L can be diagnosed with anemia.

Here is a key point: Anemia screening is not recommended when children have a fever or a cold.

Because many indicators tend to become abnormal after illness, it is best to have a physical examination when you are in good health.

However, knowing that there is a problem but not knowing what the problem is is what makes medical novices most anxious.

Does the child have an infectious disease or a non-infectious disease?

Is it a bacterial infection? Or a viral infection?

Do you have any blood disease?

If you want to understand the disease warnings behind abnormal indicators, you must first understand the different divisions of these three categories of indicators:

Three major indicators in blood routine

What disease warning is hidden behind it?

Blood cells are divided into three major categories: white blood cells, red blood cells, and platelets.

On a blood test report, these indicators are easy to distinguish: white blood cells start with "white blood cells" and end before "red blood cells." And so on.

If the human body is compared to an army, these three are soldiers with clear division of labor.

01

White blood cells: responsible for fighting foreign enemies

(Fighting on the front line)

To put it simply, white blood cells are responsible for fighting on the front line when foreign enemies invade.

When enemy forces - bacteria, viruses and other pathogens - invade the human body, white blood cells gather from all over the body to fight the enemy together.

Don’t think they only use brute force. The white blood cell “army” has a clear strategy and a clear division of labor. Some are responsible for fighting bacteria, and some are responsible for fighting viruses.

✎ Neutrophils

Mainly attack bacteria. When bacteria attack, the body will quickly produce a large number of neutrophils to fight on the "front line". At this time, the total number of white blood cells and the proportion of neutrophils in the blood will increase.

✎ Lymphocytes

If the invading virus is a virus, the lymphocytes will turn on their radar, accurately identify it, and fight it head-on.

During the battle, lymphocytes replicate in large numbers and increase in number rapidly. After the virus is defeated, the number of lymphocytes returns to normal.

02

Red blood cells: oxygen carriers

(Supply of food and fodder)

Red blood cells are responsible for transporting oxygen to all parts of the body and transporting carbon dioxide produced by metabolism.

If the number and shape of red blood cells are abnormal, it may affect the blood's ability to transport oxygen and even affect the child's growth and development.

There is another important protein in red blood cells - hemoglobin.

Hemoglobin contains iron. If the body does not take in enough iron or is malnourished for a long time, there will be a shortage of raw materials for the synthesis of hemoglobin, which will affect the production and function of red blood cells and cause anemia.

03

Platelet system: responsible for blood coagulation and hemostasis

(Logistics and maintenance)

When the body is bumped or injured and blood vessels are damaged, platelets, the "repair workers", are needed.

If the platelet count is too low: the body's ability to stop bleeding decreases. Once a blood vessel is damaged, bleeding may not stop and it may be difficult to stop bleeding.

If the platelet count is too high: The blood may clot, causing blood clots.

In short, high or low platelet count is not good.

This abnormality is found in the blood routine report

Beware of leukemia

After getting the blood test report, although it is not advisable to make a fuss, some abnormal indicators need to be alerted:

01

Abnormal white blood cell parameters

Disease warning behind

Generally, when a child has a cold or fever, you just need to look at the white blood cell count, which is often high at this time.

The total white blood cell count, neutrophil ratio, and lymphocyte ratio generally require comprehensive analysis to distinguish between bacterial infection and viral infection.

How to distinguish? The table above -

Take note: When your baby is emotionally agitated or vomiting, his white blood cell count will also increase. If there is no evidence of infection and only a slight increase in the total white blood cell count, do not use antibiotics and recheck after three days.

02

Abnormal red blood cell parameters

Disease warning behind

Changes in red blood cells and hemoglobin are usually synchronized.

Increased: It may be caused by hemoconcentration due to dehydration caused by vomiting, diarrhea, etc.

Low: May mean anemia.

Take note: If hemoglobin and platelets are low, and the total white blood cell count is abnormally high or low, be alert to leukemia and a bone marrow examination will be needed for further diagnosis.

03

Abnormal platelet parameters

Disease warning behind

When the platelet count is less than 100×10^9/L, it is thrombocytopenia.

It is more common in cases of excessive platelet destruction or excessive consumption caused by certain diseases or drugs.

When the platelet count is > 450×10^9/L, it is thrombocytosis.

Common causes include: anemia or blood loss; viral, bacterial, mycobacterial or fungal infection; non-infectious inflammation (such as malignant tumors, rheumatic diseases); after splenectomy.

The mean platelet volume is used to assess the size of platelets.

If the platelet volume is too large, the hemostatic function will decrease, and even if the number is normal, hemostasis may be difficult.

The most worrying thing about blood routine report is that you will "add drama"

Avoid these 3 common misunderstandings

✎ Many arrows in blood routine test = serious illness?

At present, there is no reference value standard for blood routine test for children in China. The reference values ​​for blood routine test in many hospitals are based on the normal range for adults.

The normal values ​​of various indicators in children's blood are different from those in adults.

Even for children, there are slight differences in various indicators at different age groups.

✎ Increased white blood cells and neutrophils = bacterial infection?

An increase in lymphocyte count and ratio may also indicate a bacterial infection.

For example: Bordetella pertussis, Mycobacterium tuberculosis, Brucella, etc.

In some serious bacterial infections, the total white blood cell count and neutrophil count may even decrease.

In addition, chronic inflammation caused by blood system tumors, autoimmune diseases, etc. can also lead to changes in the number of white blood cells.

✎ White blood cell count exceeds normal value = leukemia?

White blood cell count exceeds normal value ≠ leukemia

Vigorous exercise, physical or mental stress, non-infectious inflammation, tumors, tissue necrosis, etc. may all cause an increase in white blood cells.
