Typical diagnostic tests for Sjögren's include Schirmer's eye test, slit-lamp test, tests measuring saliva flow, radiologic salivary scans, and salivary gland biopsy.
Beta-2 Microglobulin in Whole Unstimulated Saliva (sB2M) Can Effectively Distinguish Between Sjögren’s Syndrome (SS) and Non–Autoimmune Sicca Symptoms. In our setting, sB2M effectively distinguished between SS patients and non–autoimmune sicca symptoms and including sB2M in our conventional diagnostic arsenal may assist in the evaluation of patients in whom SS is suspected.

Prevalence of distal renal tubular acidosis in primary Sjögren's syndrome (pSS). Furosemide and fludrocortisone (FF) cannot replace NH4Cl in testing urinary acidification in pSS, but may be considered as a screening tool. PubMed, Rheumatology (Oxford), 2014 Oct 29.
Antibodies to aquaporins (AQPs) are frequent in patients with primary Sjögren’s syndrome (SS). Antibodies to AQPs (especially to AQP8 and AQP9) are frequent in SS patients and the likely important role of AQPs in salivary gland secretions justifies further research. Rheumatology, 08/31/2017.
New study to investigate how good antibodies go bad. New research aims to re–examine whether IgM, a seemingly harmless antibody, is pathogenic, or capable of causing disease. University at Buffalo News Center, 01/13/2016.
Antibodies to interferon-inducible protein-16 in primary Sjögren's syndrome are associated with markers of more severe disease. Anti-IFI16 antibodies are a prominent specificity in primary SS and are associated with markers of severe disease. PubMed, Arthritis Care Res (Hoboken), 06/02/2015.
High fidelity between saliva proteomics and the salivary glands' biological state defines biomarker-signatures for primary Sjögren's syndrome (SS). The SS-related molecular landscape conveyed by saliva showed great congruence with histopathology features evoked by SS and advances understanding of this disease at a molecular level.

Establishment of a novel diagnostic model for Sjögren's syndrome (pSS) by proteomic fingerprinting. Proteomic fingerprinting was able to distinguish pSS from non-pSS controls with a sensitivity of 77.1 % and a specificity of 85.5 %, and was effective in the diagnosis of pSS. PubMed, Clin Rheumatol, 2014 Sep 2.
Nailfold capillaroscopic findings in primary Sjögren's syndrome with and without Raynaud's phenomenon and/or positive anti-SSA/Ro and anti-SSB/La antibodies. Patients with RP associated with PSS had more dilated capillaries, but neither pericapillary haemorrhages nor capillary thrombosis was observed. PubMed, Rheumatol Int, 11/23/2015. (Also see Diagnosis of Primary Raynaud's using Nailfold Capillaroscopy)
Neurological adverse events related to lip biopsy in patients suspicious for Sjögren's syndrome (SS). The minimally invasive lip biopsy technique for SS diagnosis induces fewer permanent neurological complications than conventional approaches. PubMed, Rheumatology, 2014 Mar 4.
Schirmer's Test. This is also known as a dry eye test, a tear test, or a tearing test. The Schirmer's test determines whether the eye produces enough tears to keep it moist. Paper strips are inserted under the eyelid. Before the test, you may be given numbing eye drops to prevent tearing due to the irritation from the paper. Most often, the eyes are closed for about 5 minutes. Medline Plus, NIH.
Slit Lamp Examination. The slit lamp exam uses an instrument that provides a magnified, three-dimensional (3-D) view of the different parts of the eye. During the exam, your health professional can look at the front parts of the eye, including the clear, outer covering (cornea), the lens, the colored part (iris), and the front section of the gel-like fluid (vitreous gel) that fills the large space in the middle of the eye.

Scoring hypoechogenic areas in one parotid and one submandibular gland increases feasibility of ultrasound in primary Sjögren's syndrome. Ultrasound examination of the parotid and submandibular glands on one side is sufficient to predict classification of patients according to the ACR–EULAR criteria. PubMed, Ann Rheum Dis, 12/11/2017.
Diagnostic properties of ultrasound of major salivary glands in Sjögren's Syndrome: a meta-analysis. The quality of current studies is low, thus not allowing to judge the likelihood of salivary gland ultrasonography as a reliable and practical tool in diagnosing Sjögren's Syndrome. PubMed, Oral Dis, 05/18/2015.
Salivary Gland Ultrasonography (US) as a Diagnostic Tool for Secondary Sjögren Syndrome (sSS) in Rheumatoid Arthritis (RA). Salivary gland US may aid the diagnosis of sSS in patients with RA. PubMed, J Rheumatol, 05/01/2015. (Also see Rheumatoid Arthritis in Overlap)
The role of salivary gland elastosonography in Sjögren's syndrome (SS): preliminary results. With the progression of Sjögren's, the elasticity scores of the parotid glands increase gradually, indicating that ultrasonic elastosonography has the potential to demonstrate the progression of the disease. PubMed, Int J Rheum Dis, 2014 Sep 15.
