It seems that the OTC applicable article keeps getting cited by posters like you. OTC trades always involve market-makers. It is the market-makers that make temporary short sales that get listed with FINRA, and this is the cause of short volume inaccuracies with OTC trading. CODX is traded on the NASDAQ exchange and the others are also exchange trades, NOT OTC trades!!!! The OTC article is NOT relevant here!!!! Short volumes allow investors the ability to track illegal stock manipulation activities. The recent implementation of the Consolidated Audit Trail now allows the SEC to monitor illegal stock manipulation, and, theoretically, should make the need to follow short volumes unnecessary providing someone is actually monitoring the illegal manipulation.
