In laboratory reporting, TS/TP refers to which measurements?

• A. Total solids or total protein
• B. Tissue solids or total protein
• C. Transfusion schedule/total protein
• D. Total solids or tri-phosphates

Answer: (A)

TS/TP on a laboratory report denotes two common measurements: total solids and total protein. Total solids represent all dissolved solids in a liquid sample—often used with urine to gauge how concentrated the urine is and to assess hydration status. Total protein reflects the amount of protein present in a fluid sample, typically measured in serum or plasma to evaluate nutritional status, liver function, and other conditions. Laboratories may report TS or TP under the same label because some instruments, especially refractometer-based or point-of-care methods, can provide either value depending on the sample being tested. The other options don’t fit because tissue solids isn’t a standard lab metric, transfusion schedule isn’t a laboratory measurement, and tri-phosphates aren’t relevant to this reporting label.
