Which statement about dating bruising is true?

• A. Bruising Can Be Dated Precisely
• B. Bruising Cannot Be Dated
• C. Bruising Can Be Dated By Blood Tests
• D. Bruising Appears Immediately After Injury

Answer: (B)

Dating a bruise with precision isn’t reliable. The color changes seen in bruises come from the breakdown of blood components, but the timing of those changes varies widely from person to person and is affected by skin tone, where on the body the injury is, how severe it was, and individual healing factors like age and medications. Because of this variability, two bruises that look similar can be from different ages, and the same bruise can look different in different people. There’s no blood test or laboratory marker that can pin down the exact day a bruise formed, and bruising isn’t usually visible immediately after an injury. All of this means you can’t date a bruise precisely; at best you can estimate a broad time frame based on overall appearance and context.
