Answer :
The most common antiseptic used for a routine blood collection is 70% isopropyl alcohol. Here's why:
1. **Effectiveness**: Isopropyl alcohol is a commonly used antiseptic because it effectively kills bacteria and sterilizes the skin, reducing the risk of infection during blood collection.
2. **Availability**: Isopropyl alcohol is readily available in healthcare settings, making it a convenient choice for routine procedures like blood collection.
3. **Convenience**: It is easy to use and dries quickly, allowing healthcare professionals to efficiently prepare the skin before drawing blood.
4. **Safety**: Isopropyl alcohol is considered safe for use on the skin and is less harsh compared to alternatives like bleach, which can be too strong and cause skin irritation.
While other antiseptics like iodine (such as Betadine) can also be used for blood collection, 70% isopropyl alcohol is the most common choice due to its effectiveness, availability, convenience, and safety.
