Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Reporting	The accompanying unaudited interim condensed financial statements of American Bio Medica Corporation (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Regulation S-X. Accordingly, these unaudited interim condensed financial statements do not include all information and footnotes required by U.S. GAAP for complete financial statement presentation. These unaudited interim condensed financial statements should be read in conjunction with audited financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. In the opinion of management, the interim condensed financial statements include all normal, recurring adjustments which are considered necessary for a fair presentation of the financial position of the Company at June 30, 2018, and the results of operations and cash flows for the three and six month periods ended June 30, 2018 and June 30, 2017. Operating results for the six months ended June 30, 2018 are not necessarily indicative of results that may be expected for the year ending December 31, 2018. Amounts at December 31, 2017 are derived from audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. During the six months ended June 30, 2018, there were no significant changes to the Company’s critical accounting policies, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The preparation of these interim condensed financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates estimates, including those related to product returns, bad debts, inventories, income taxes, warranty obligations, contingencies and litigation. The Company bases estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. These unaudited interim condensed financial statements have been prepared assuming that the Company will continue as a going concern and, accordingly, do not include any adjustments that might result from the outcome of this uncertainty. The independent registered public accounting firm’s report on the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, contained an explanatory paragraph regarding the Company’s ability to continue as a going concern. As of the date of this report, the Company’s current cash balances, together with cash generated from future operations and amounts available under the Company’s credit facilities may not be sufficient to fund operations through August 2019. The Company’s current line of credit matures on June 29, 2020. The maximum availability on the Company’s line of credit remains to be $1,500,000. However, the amount available under the Company’s line of credit is based upon the Company’s accounts receivable and inventory. As of June 30, 2018, based on the Company’s availability calculation, there were no additional amounts available under the Company’s line of credit because the Company draws any balance available on a daily basis. As discussed in more detail in “Cash Flow, Outlook/Risk”, if sales levels decline further, the Company will have reduced availability on its line of credit due to decreased accounts receivable balances. In addition, the Company would expect its inventory levels to decrease if sales levels decline further, and this would also result in reduced availability on the Company’s line of credit. In addition to this reduced availability, in June 2018, the Company’s line of credit was amended to reduce the maximum availability under the inventory component of its line of credit over the next 25 months. While this will not result in a dramatic impact to our availability today, it will ultimately remove availability related to our inventory under the line of credit. If availability under the Company’s line of credit is not sufficient to satisfy its working capital and capital expenditure requirements, the Company will be required to obtain additional credit facilities or sell additional equity securities, or delay capital expenditures. There is no assurance that such financing will be available or that the Company will be able to complete financing on satisfactory terms, if at all. Recently Adopted Accounting Standards The Company adopted the following accounting standards set forth by the Financial Accounting Standards Board (“FASB”): ASU 2014-09, “Revenue from Contracts with Customers”, issued in May 2014, provides guidance for revenue recognition. The core principle of ASU 2014-09 is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current guidance. Examples of the use of judgments and estimates may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The update also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 provides for two transition methods to the new guidance: a retrospective approach and a modified retrospective approach. In August 2015, ASU 2015-14, “Revenue from Contracts with Customers: Deferral of the Effective Date” was issued as a revision to ASU 2014-09. ASU 2015-14 revised the effective date to fiscal years, and interim periods within those years, beginning after December 15, 2017. Subsequently, additional updates were issued related to this topic, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20. Early adoption of ASU 2014-09 was permitted but not prior to periods beginning after December 15, 2016 (i.e. the original adoption date per ASU No. 2014-09). The Company's revenues result from the sale of goods and reflect the consideration to which the Company expects to be entitled. The Company records revenues based on a five-step model in accordance with ASU 2014-09. The Company has defined purchase orders as contracts in accordance with ASU 2014-09. For its customer contracts, the Company’s performance obligations are identified; which is delivering goods at a determined transaction price, allocation of the contract transaction price with performance obligations (when applicable), and recognition of revenue when (or as) the performance obligation is transferred to the customer. Goods are transferred when the customer obtains control of the goods (which is upon shipment to the customer). The Company's revenues are recorded at a point in time from the sale of tangible products. Revenues are recognized when products are shipped. The Company has elected the Modified Retrospective Method (the "Cumulate Effect Method") to comply with ASU 2014-09. The Cumulative Effect Method does not affect the amounts for the prior periods, but requires that the current period be reported in accordance with ASU 2014-09. ASU 2014-09 was adopted on January 1, 2018 which was the first day of the Company's 2018 fiscal year. There was no material impact on the Company’s financial position or results of operations. Product returns, discounts and allowances are variable consideration and are recorded as a reduction of revenue in the same period that the related sale is recorded. The Company has reviewed the overall sales transactions for variable consideration and has determined that these costs are not significant. The Company has not experienced any impairment losses, has no future performance obligations and does not capitalize costs to obtain or fulfill contracts. Accounting Standards Issued; Not Yet Adopted ASU 2016-02, “Leases”, issued in February 2016, requires a lessee to recognize a lease liability and a right-of-use asset on its balance sheet for all leases, including operating leases, with a term greater than 12 months. Lease classification will determine whether a lease is reported as a financing transaction in the income statement and statement of cash flows. ASU 2016-02 does not substantially change lessor accounting, but it does make certain changes related to leases for which collectability of the lease payments is uncertain or there are significant variable payments. Additionally, ASU 2016-02 makes several other targeted amendments including a) revising the definition of lease payments to include fixed payments by the lessee to cover lessor costs related to ownership of the underlying asset such as for property taxes or insurance; b) narrowing the definition of initial direct costs which an entity is permitted to capitalize to include only those incremental costs of a lease that would not have been incurred if the lease had not been obtained; c) requiring seller-lessees in a sale-leaseback transaction to recognize the entire gain from the sale of the underlying asset at the time of sale rather than over the leaseback term; and d) expanding disclosures to provide quantitative and qualitative information about lease transactions. ASU 2016-02 is effective for all annual and interim periods beginning January 1, 2019, and is required to be applied retrospectively to the earliest period presented at the date of initial application, with early adoption permitted. The Company is evaluating the impact of ASU 2016-02. ASU 2017-11, “Earnings Per Share, Distinguishing Liabilities from Equity, Derivatives and Hedging”, issued in July 2017, changes the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature will no longer preclude equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) would not be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (EPS) in accordance with Topic 260 to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features are now subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). ASU 2017-11 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of ASU 2017-11. ASU 2018-07, “Compensation - Stock Compensation/Improvements to Nonemployee Share-Based Payment Accounting”, issued in June 2018, expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The requirements of Topic 718 must be applied to nonemployee awards except for certain exemptions specified in the amendment. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018, including interim reporting periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is evaluating the impact of ASU 2018-07. There are no other accounting pronouncements issues during the six months ended June 30, 2018 that are expected to have or that could have a significant impact on our financial position or results of operations. Reclassifications Certain items have been reclassified from the prior year to conform to the current year presentation.
