What three tests are included in the "three infection tests" of a complete blood count?

Generally speaking, there is no such term as "three items for blood routine related to infection." The so-called "infection trio" usually refers to testing for human immunodeficiency virus (HIV) antibodies, syphilis treponema antibodies, and hepatitis virus markers; while the "three blood routine items" refer to red blood cell count, white blood cell count, and platelet count. Patients are advised to follow medical guidance for appropriate treatment. Specific analysis is as follows:

1. Infection Trio

The "infection trio" refers to three infectious marker tests: human immunodeficiency virus (HIV) antibody test, Treponema pallidum (syphilis) antibody test, and hepatitis virus marker test. These are mandatory tests required before surgery and essential screenings prior to any medical procedure. The HIV antibody test detects antibodies against HIV-1 and HIV-2 and serves as the gold standard for diagnosing HIV infection. The syphilis antibody test includes both non-treponemal and treponemal serological tests. The hepatitis virus marker test determines whether an individual has been infected with hepatitis virus.

2. Three Blood Routine Items

The "three blood routine items" refer to the most critical components in a complete blood count (CBC): red blood cell (RBC) count, white blood cell (WBC) count, and platelet count. By analyzing RBCs and hemoglobin levels in the CBC, one can determine the presence of anemia. Abnormalities in the number and quality of WBCs provide important clues about recent or ongoing inflammation in the body. Platelet testing helps assess whether the body's coagulation system is functioning properly. CBC is a standard component of routine health check-ups and inpatient blood testing.

If a patient experiences any discomfort or symptoms, it is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
