The T cell response to beryllium, measured in bronchoalveolar lavage by the lymphocyte transformation test (LTT), is a critical diagnostic test for discriminating between chronic beryllium disease (CBD) and other granulomatous diseases. We examined the sensitivity, reproducibility, and methods of a less invasive, peripheral blood LTT in 17 patients with CBD and in 18 beryllium-exposed control subjects. Ninety-four percent of CBD cases (16/17) had abnormal blood LTT results, and all 18 beryllium-exposed control subjects had normal blood LTT results. Split samples for 10 beryllium disease cases and eight control subjects demonstrated that the blood LTT was reproducible between two separate laboratories. The LTT was equally sensitive with 10% and 20% serum in the culture medium. We conclude that an abnormal blood LTT can be used to diagnose CBD in patients with compatible lung pathology.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D001607	Berylliosis	A form of pneumoconiosis caused by inhaled rare metal BERYLLIUM or its soluble salts which are used in a wide variety of industry including alloys, ceramics, radiographic equipment, and vacuum tubes. Berylliosis is characterized by an acute inflammatory reaction in the upper airway leading to BRONCHIOLITIS; PULMONARY EDEMA; and pneumonia.	Beryllium Disease,Beryllioses
D001608	Beryllium	An element with the atomic symbol Be, atomic number 4, and atomic weight 9.01218. Short exposure to this element can lead to a type of poisoning known as BERYLLIOSIS.
