HVS can refer to two different things: Hyperviscosity Syndrome and High Vaginal Swab.
Hyperviscosity Syndrome (HVS) is a medical condition that refers to the clinical sequelae of increased blood viscosity. It usually results from increased circulating serum immunoglobulins and can be seen in diseases such as Waldenström macroglobulinemia and multiple myeloma. HVS can also result from increased cellular blood components in hyperproliferative states such as the leukemias, polycythemia, and the myeloproliferative disorders. The clinical presentation in HVS consists principally of the triad of mucosal bleeding, visual changes, and neurologic symptoms. Constitutional symptoms and cardiorespiratory symptoms may also occur. The diagnosis of HVS is confirmed by measurement of elevated serum viscosity in a patient with characteristic clinical manifestations of HVS.
On the other hand, High Vaginal Swab (HVS) is a medical procedure performed in obstetrics and gynecology to test vaginal discharge for the presence of vaginal thrush, bacterial vaginosis, trichomonas vaginalis, and other infections. It is a simple test done in a doctors office or clinic. The test detects infections in the vagina and cervix, and it can help detect infections that can cause serious health problems, such as pelvic inflammatory disease, infertility, and cancer. The HVS test can also detect STDs such as HPV, chlamydia, trichomoniasis, and gonorrhea.
