Why do Emergency Rooms Take Blood? 15 Reasons

One of the most effective ways of knowing what ails one’s body by drawing blood. A person’s blood can reveal much about the inside of the body than any other form of diagnosis. Blood draw by a family doctor or a clinic is common for most people but what most people still do not know and understand is that emergency rooms also need to draw blood as part of their treatment process. If you are wondering why and for what purpose physicians draw blood in the Emergency Room, here are the reasons highlighted by Bellaire ER.

1. To check for infections
The infectious organisms that cause illness mostly dwell in the blood system of the patient. Drawing a blood sample and analyzing the same helps in identifying these disease-causing organisms hence facilitating the administration of the right treatment.

2. To check for Anemia
If you have experienced blood loss or if there is a concern that you have anemia, the physicians in the Emergency Room will have to get a blood sample from you and conduct Complete Blood Count. This is a procedure for checking one’s red and white blood cells count. Anemia, when ignored or not diagnosed early, may result in death.

3. For a Chemistry profile
A chemistry profile is a test that helps quickly determine whether a person has a number of health issues like diabetes, heart attack, dehydration and kidney and liver functions among others. The blood circulates through all parts and organs in the body hence it can provide more accurate information about your body condition.

4. To determine the correct dosage of blood thinner to be administered to the patient
If a patient is on a blood thinner, blood is usually drawn and a Protime test done. This test is meant to ensure that your blood is safe and at a healthy level. The test helps the doctor determine the adjustment they need to make and ensure the patient takes the correct blood thinner dose.

5. To determine how the body will react to drugs
Some drugs are very vigorous in action and can cause harm when administered instead of improving the health condition of the patient. A blood test comes in handy in determining the types of drugs to administer by helping identify those that can cause a negative reaction to the body.

6. To check for blood types
A patient might require a blood transfusion. For a person to receive blood from another person, they have to be of the same blood group, and the only way to determine a person’s blood group is by drawing blood and conducting a blood test.

7. To check for possibility of other drugs in the patient’s system
Drugs happen to be very sensitive substances. It is, therefore, important that before a drug is administered to counter a particular condition, the blood is checked not to contain any other drug that may have been prescribed to the patient before. If two drugs happen to be in the blood system at the same time, the results may be catastrophic rather than helpful.

8. To check for illegal substances
If a patient is a junkie or has ingested an illegal substance into their system, drawing of their blood will help identify the substance and flash it out before treatment is administered.

9. To determine if a woman is pregnant
Treating a woman without considering her pregnancy status may endanger her life and that of her unborn child. Blood tests are important when it comes to determining whether a woman is pregnant or not. The results will help guide the doctors in the treatment to administer.

10. To determine if a patient has had an overdose
Drawing blood and conducting blood tests can help tell if a patient has had an overdose of a drug and also help identify that particular drug.

11. Drawing blood helps measure the PH levels and the amount of oxygen and carbon dioxide present in a patient’s system in the blood.

12. To help in diagnosis of issues related to diabetes
A simple blood test can help reveal the blood sugar levels and any other issues that may be as a result of diabetes. Diabetes usually triggers the occurrence of other signs and symptoms in the body that can be easily revealed by a blood test.

13. For immunology
This is basically monitoring of the condition of one’s immune system. The test helps check the antibodies present in one’s blood stem and hence help evaluate how strong their immune system is.

14. Checking for blood cholesterol level and other issues related to heart attack
Drawing of blood in the Emergency Room will help in the diagnosis on one’s cholesterol level in the blood and other issues that may be the cause of a heart attack.

15. For blood clotting tests
In case a patient has bled excessively due to a damaged vessel, a blood clotting test can help reveal the problem and help treat it fast. Bleeding disorders can result in anemia and eventually death.
