Summarize this article for a 10 year old
The Alvarado score is a clinical scoring system used in the diagnosis of appendicitis.[1] Alvarado scoring has largely been superseded as a clinical prediction tool by the Appendicitis Inflammatory Response score.[2][3][4]
Also known by the mnemonic MANTRELS, the scale has 6 clinical items (3 signs and 3 symptoms) and 2 laboratory measurements, each given an additive point score, with a maximum of 10 points possible.[5] It was introduced in 1986 by Dr. Alfredo Alvarado and although meant for pregnant females, it has been extensively validated in the non-pregnant population. A known limitation of the score is that only 20% of elderly patients present with classic findings on which the score focuses.[5] A modified Alvarado score is at present in use.[6]
