The anticoagulant most ccommonly used to store blood in the blood banks is

Options

A. sodium citrate
B. sodium fluoride
C. EDTA
D. acid citrate dextrose

Answer

To solve the question regarding the anticoagulant most commonly used to store blood in blood banks, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Anticoagulants**:
- Anticoagulants are substances that prevent blood from clotting. They are essential in blood banks to ensure that the blood remains in a liquid state for storage and transfusion.

2. **Evaluate the Options**:
- The question provides four options for anticoagulants. We need to analyze each one to determine which is most commonly used in blood banks.

3. **Option Analysis**:
- **Option 1: Sodium Citrate**:
- Sodium citrate is primarily used to make blood and urine more alkaline. It is not the most common anticoagulant used for blood storage.
- **Option 2: Sodium Fluoride**:
- Sodium fluoride is used as an anticoagulant in specific tests, such as blood phosphorus determinations, but it is not commonly used for blood storage.
- **Option 3: EDTA (Ethylenediaminetetraacetic acid)**:
- While EDTA is an effective anticoagulant, it is mainly used for hematological tests and not primarily for blood storage in blood banks.
- **Option 4: Acid Citrate Dextrose (ACD)**:
- ACD is a solution that contains citric acid, sodium citrate, and dextrose. It is specifically designed for blood preservation and is commonly used in blood banks to store blood.

4. **Conclusion**:
- After evaluating all the options, the correct answer is **Option 4: Acid Citrate Dextrose (ACD)**, as it is the most commonly used anticoagulant for storing blood in blood banks.

### Final Answer:
The anticoagulant most commonly used to store blood in the blood banks is **Acid Citrate Dextrose (ACD)**.
