As we go about our lives our body also changes with time. Environmental Factors like diet and lifestyle play a major role in our life expectancy. In fact, it is found that genes actually have a small role in this.
Therefore it may require changing our lifestyle now and then, especially in this fast-paced world. While gradually our body takes its toll, it is all the more a total necessity to get a blood test checkup.
You might look and feel completely healthy, but it doesn’t show whether there’s actually something wrong with your body until you go to the doctor and get a complete blood test checkup.
Blood test checkups do not only diagnose disease; they can catch a whole host of potential health problems while they’re still in their early stages and allow you to manage them through early intervention by blood test checkups.
Complete Blood test checkup is a quick and easy procedure and can help monitor blood sugar, heart disease risk factors, hormone balance, mineral balance, liver and kidney function, and levels of red and white blood cells, among many other things.
A blood test checkup is the single most important test you can get to prevent, diagnose and manage a wide variety of diseases and conditions, and it’s vital to have a complete blood test checkup regularly.
The basic function of Blood Test
Complete blood tests help doctors diagnose certain diseases and conditions. They also help check the function and conditions of your blood and show how well ongoing treatments are working. To be precise, complete blood test checkups can help doctors: determine how organs—such as the kidneys, liver, thyroid, and heart—are working, enabling you to take timely precautions and adjustments regarding your health. This is why it is recommended to make regular complete blood test checkups an integral part of our life.

How often should you do the blood test?
Your doctor will advise that you get a routine complete blood test checkup, around the same time as your yearly physical at a diagnostic testing center at least once a year, at around the same time as other physical examinations.
you should get a blood test checkup more often if you’re 40 and above and with chronic illness.
The same when applied you experience persistent or unusual symptoms, such as fatigue, skin or nail abnormalities, hair loss, or weight gain.
Units of measurement in Blood Test Checkup
Lab test results usually practice some type of unit of measurement. The units provide a way to report results so that they can be compared and help the diagnosis process. Generally, but not always, the same blood test checkup test is reported in the same units no matter which lab did the test. Some of the units of measurement that is used for lab test are listed below:
Grams per decilitre (g/dL).
Grams per liter (g/L).
International units per liter (IU/L).
What is a red blood cell count?
A red blood cell count is a blood test that is used to find out how many red blood cells (RBCs) you have. It’s also known as an erythrocyte count.
The blood test is important because RBCs contain hemoglobin, which carries oxygen to your body’s tissues. How much oxygen your tissues receive can be affected by the number of RBCs you have. Your tissues need oxygen to function. Symptoms of an abnormal count
If your RBC’s normal range is too high or too low, you could experience symptoms and complications.
If your RBC count is low, symptoms could include:
- shortness of breath
- dizziness, weakness, or lightheadedness, particularly when your position change quickly or suddenly
- increased heart rate
- pale skin
- joint pain
- itching skin, particularly after a shower or bath
- sleep disturbance
What is the RBC normal range of the RBC count?
The normal RBC normal range for men is 4.7 to 6.1 million cells per microliter (MCL).
The normal RBC normal range for women who aren’t pregnant is 4.2 to 5.4 million mcL.
The normal RBC normal range for children is 4.0 to 5.5 million mcL.
However, ranges may vary depending on the laboratory or doctor.
WBC count and WBC normal range
A blood test to measure WBC’s normal range and the number of white blood cells (WBCs) in the blood is called a WBC count.
WBCs are also called leukocytes. They help fight infections. The five major types of white blood cells:
Why the Test is Performed?
This test is taken to find out how many WBCs you have by comparing with you your WBC normal range and help diagnose conditions such as:
Blood cancer such as leukemia or lymphoma
In WBC normal range in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L).
WBC normal range values may vary slightly among different labs. Results may vary because labs use different measurements or may test different specimens. Consult the provider about your test results.
What do Abnormal Results mean?
LOW WBC COUNT
A low WBC normal range is called leukopenia. Beyond WBC normal range or a count, less than 4,500 cells per microliter (4.5 × 109/L) is below normal.
Neutrophils are one type of WBC. They are crucial for fighting infections.
A lower than WBC normal range may be due to:
- Bone marrow deficiency or failure (for instance, due to infection, tumor, or abnormal scarring)
- Cancer treatment drugs, or other medicines
- Certain autoimmune disorders such as lupus (SLE)
- A disease of the liver or spleen
- Radiation treatment for cancer
- Certain viral illnesses, such as mononucleosis (mono)
- Cancers that damage the bone marrow
- Very severe bacterial infections
- physical stress or severe emotional stress (such as from an injury or surgery)
Blood test checkup components
Component 1: CBC
Complete blood count CBC blood test is a blood test used to assess your overall health and detect a wide range of disorders, including infection of anemia, and leukemia.
A complete blood count, CBC blood test measures the number of different components and features of your blood, including:
Red blood cells normal range, which carries oxygen
White blood cells normal range, which fight infection
Hemoglobin, the oxygen-carrying protein in red blood cells
Hematocrit, the number of red blood cells to the fluid component, or plasma, in your blood.
Platelets, which help with blood clotting
Abnormal behaviors leading to the increases or decreases in cell counts as discovered in a complete blood count may indicate that you have an underlying medical condition that calls for further evaluation CBC blood test
Component 2: Erythrocyte Sedimentation ratio(ESR)
A blood test checkup that can reveal inflammatory activity in your body rate or erythrocyte (ESR) A sed rate test isn’t a complete diagnostic tool, but it can surely help to monitor or diagnose the progress of the inflammatory disease.
Blood is put in a tall, thin tube, red blood cells (erythrocytes) slowly settle to the bottom. Inflammation can cause the cells to clump. These clumps settle to the bottom more quickly because these clumps are denser than individual cells.
Measuring the distance red blood cells fall in a test tube in one hour is the process of sed rate. The further the red blood cells have descended, the greater the inflammatory response of your immune system.
Your doctor may order a blood sugar test as part of a routine checkup. And may also be looking to see if you have diabetes or prediabetes, a condition where your blood sugar levels are higher than norming factors when interpreting the results of your sed rate test.
Component 3: BST(Blood sugar test)
A blood sugar test in blood test checkup is a process that measures the amount of sugar, or glucose, in your blood. Your doctor may recommend this test to help diagnose diabetes. People with diabetes can benefit from this test to manage their condition.
Your doctor may order a blood sugar test as part of a routine blood test checkup. And may also be looking to see if you have diabetes or prediabetes, a condition where your blood sugar levels are higher than norming factors when interpreting the results of your sed rate test.
Component 4: Lipid profile
Lipid panel or lipid profile is known as complete cholesterol test — is a blood test checkup that can measure the amount of cholesterol and triglycerides in your blood.
A cholesterol test can help predict your risk of the buildup of fatty deposits (plaques) in your arteries that can lead to narrowed or blocked arteries throughout your body (atherosclerosis).
A cholesterol test is an important tool. because High cholesterol levels often are a significant risk factor for coronary artery disease.
All cholesterol test includes the calculation of four types of fats in your blood:
This is the sum of your blood’s cholesterol content.
Low-density lipoprotein (LDL) cholesterol.
This is called the “bad” cholesterol. Too much of it in your blood causes the building up of fatty deposits (plaques) in your arteries (atherosclerosis), which reduces blood flow. These plaques sometimes burst and can lead to a heart attack or stroke.
High-density lipoprotein (HDL) cholesterol.
This is called the “good” cholesterol because it helps carry away LDL cholesterol, which keeps arteries open and your blood flowing more freely.
Who should get a cholesterol test?
It is recommended to have frequent testing if your initial test results were abnormal or if you already a coronary artery disease patient, or under cholesterol-lowering medications or you’re prone to a higher risk of coronary artery disease because you:
Have a family history of high cholesterol or heart attacks
Are physically inactive
Eat an unhealthy diet
For people undergoing treatment for high cholesterol, it’s necessary to have cholesterol testing to monitor the effectiveness of their treatments.
Component 5: Kidney test
(BUN) The blood urea nitrogen test is a common blood test that exposes important information about how well your kidneys and liver are working. A BUN test is the amount of urea nitrogen that’s in your blood.
A BUN test can determine whether your urea nitrogen levels are higher than normal, suggesting that your kidneys or liver may not be working properly
As part of a blood test plan to help diagnose a number of other conditions, such as liver damage, urinary tract obstruction, congestive heart failure, or gastrointestinal bleeding — however, an abnormal BUN test result alone doesn’t confirm any of these conditions
When kidney problems are the main concern, the creatinine levels in your blood will likely also be measured when your blood is tested for urea nitrogen levels. Healthy kidneys filter out creatinine which is another waste product through which urine is filtered. High levels of creatinine in your blood may suggest kidney damage.
Component 6: Liver test
Liver function tests are blood tests used for diagnosing and monitoring liver disease or damage. The tests are accurate in measuring the levels of certain enzymes and proteins in your blood.
Part of these tests shows how the liver is performing its normal functions of producing protein and clearing bilirubin, a blood waste product. Other liver function tests evaluate enzymes that liver cells release in response to damage or disease.
Your doctor will explain your results and what they mean as the liver function test result doesn’t always indicate liver disease.
Component 7: Uric Acid Test
What is a uric acid test?
A waste product that’s found when the body breaks down chemicals are called purines. Purines are substances found in your own cells and also in some foods. Foods that have high levels of prunes are liver, anchovies, sardines, dried beans, and beer.
Usually uric acid dissolves in your blood, then goes to the kidneys. From there, it passes out of the body through your urine. When your body makes too much uric acid or doesn’t release enough into your urine, it can make crystals that form in your joints known as gout. Gout is another form of arthritis that is a painful inflammation in and around the joints. High uric acid levels may also cause disorders, including kidney stones and kidney failure.
Component 8: The thyroid blood test
Why are they taken and what are thyroid blood tests?
Thyroid blood tests determine if your thyroid gland is functioning properly by measuring the number of thyroid hormones in your blood. They are taken by withdrawing blood from a vein in your arm. These blood tests can help to diagnose thyroid diseases.
The thyroid is a butterfly-shaped gland and is located in the front part of your neck. Its job is to produce thyroid hormones, which travel through your bloodstream and mobilize many aspects of your body’s metabolism, including temperature, weight, and energy
What do the results mean?
Test results will vary based on your blood cell counts. Here are the normal results for adults, but different labs may deliver slight variations:
||Blood test check-up component
|| Normal Range
||Red blood cell
||In men: 4.32-5.72 million cells/mcL in
Women:3.90-5.03 million cells/mcL
||In men:135-175 grams/L In women:
120-155 grams /L
||In men: 135-175 grams/L In women:
||white blood cell count
||3,500 to 10,500 cells/mcL
||150,000 to 450,000/mcL
Things to do before doing the Blood Test Checkup
Drink plenty of water before your appointment. …
Eat a healthy meal before you go. …
Wear a short-sleeved shirt or layers. …
taking prohibited aspirin at least two days before your blood draw if you’re donating platelets.
If your blood sample is tested only for a complete blood count, you can eat and drink before the test. But If your blood sample will be used for additional tests, you may be required to fast for a certain amount of time before the test. Your doctor will give you specific instructions.
