transudate

If the drop dissipates, the test is negative, indicating a transudate.

Rivalta test may be used to differentiate an exudate from a transudate.

It uses an fluid called oral mucosal transudate, which lives in the cheeks and gums.

A test using oral mucosal transudate, a serous fluid.

The alveoli become flooded with transudate 2) Hyaline membrane production.

(See below for difference between transudate and exudate)

Causes of high Serum-ascities albumin gradient ("transudate") are:

Serous exudate (sometimes classified as serous transudate) is usually seen in mild inflammation, with relatively low protein.

On post-mortem examination, a light yellow transudate that coagulates on exposure to air is often found within the thorax, pericardium and abdomen.

Briefly, transudate is produced through pressure filtration without capillary injury while exudate is "inflammatory fluid" leaking between cells.

In an HIV-infected person, oral mucosal transudate is likely to contain HIV antibodies.

More recent studies have examined other characteristics of pleural fluid that may help to determine whether the process producing the effusion is local (exudate) or systemic (transudate).

The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate.

Necropsy examination will usually show changes in the bursa of Fabricius such as swelling, oedema, haemorrhage, the presence of a jelly serosa transudate and eventually, bursal atrophy.

Treatment of Meigs' syndrome consists of thoracentesis and paracentesis to drain off the excess fluid (transudate), and unilateral salpingo-oophorectomy or wedge resection to correct the underlying etiology.

The traditional definitions of transudate as a pleural effusion due to systemic factors and an exudate as a pleural effusion due to local factors have been used since 1940 or earlier (Light et al., 1972).

SIR,- It has been reported that HIV-1 antibodies can be detected, with a high degree of sensitivity and specificity, in saliva and in oral mucosal transudate (OMT) from HIV-1-infected patients.

However, pleural fluid testing is not perfect, and the final decision about whether a fluid is a transudate or an exudate is based not on chemical analysis of the fluid, but on accurate diagnosis of the disease that produces the fluid.

In radiology, ground glass opacity (GGO) is a nonspecific finding on computed tomography (CT) scans that indicates a partial filling of air spaces by exudate or transudate, as well as interstitial thickening or partial collapse of lung alveoli.
